AMETEK Crystal XP2i is a precise digital pressure gauge designed for demanding pressure measurement, testing and calibration applications in the laboratory and in the field. Combining accuracy down to ±0.1% of reading, pressure ranges up to 15,000 psi / 1,000 bar, intrinsic safety and exceptional mechanical durability, the XP2i has become a widely used digital test gauge for industrial pressure measurement.
The XP2i is particularly suitable for applications where conventional mechanical pressure gauges do not provide sufficient accuracy, stability or readability. Its reading-based accuracy specification allows one XP2i to replace several conventional full-scale-based pressure gauges, reducing the number of instruments required for a broad calibration workload.
Three accuracy configurations are available. The standard XP2i provides ±0.1% of reading, while optional versions provide ±0.05% of full scale or ±0.02% of full scale accuracy. This allows the instrument to be selected according to the specific requirements of field testing, hydrostatic testing or higher-accuracy laboratory applications.
A major advantage of the AMETEK Crystal XP2i is its active digital temperature compensation. The specified accuracy is maintained across the complete operating temperature range from -10 °C to +50 °C without an additional temperature error.
The rugged marine-grade enclosure resists corrosion and environmental influences, while intrinsic safety approvals make the XP2i suitable for pressure measurement in hazardous areas.
Optional DataLoggerXP functionality transforms the XP2i from a digital pressure gauge into a portable pressure recorder. Measurement data can be stored internally and subsequently transferred for analysis and documentation.
At europascal, the AMETEK Crystal XP2i can be combined with professional pneumatic and hydraulic pressure generation equipment to create complete pressure testing and calibration systems. For professional calibration and metrological traceability, visit the europascal Calibration Service.

±0.1% of Reading Accuracy
The standard AMETEK Crystal XP2i provides pressure measurement accuracy of:
±0.1% of reading.
The reading-based specification is particularly advantageous compared with conventional pressure gauges whose accuracy is specified exclusively as a percentage of full scale.
For the standard XP2i, the ±0.1% of reading specification applies down to approximately:
20% of full-scale range.
Below this point, the applicable lower-range specification must be considered according to the selected XP2i model.
Because the measurement error decreases with the measured pressure over the reading-based portion of the range, one XP2i can replace several conventional full-scale-based pressure gauges.
Optional ±0.02% FS Accuracy
For applications requiring a full-scale-based accuracy specification, the XP2i is available in an:
±0.02% of full scale
configuration.
This version is designated with the:
-S2
ordering option.
The S2 version is particularly useful for applications where standards, procedures or customer specifications require a percentage-of-full-scale accuracy statement.
Optional ±0.05% FS Accuracy
An additional:
±0.05% of full scale
version is available.
This configuration uses the:
-S5
ordering option.
Together, the three accuracy configurations allow the XP2i to be selected according to the specific requirements of the pressure measurement application.
Pressure Ranges up to 1,000 bar
The AMETEK Crystal XP2i is available in pressure ranges extending up to:
15,000 psi
or approximately:
1,000 bar.
Metric gauge-pressure ranges include versions such as:
- 1 bar
- 2 bar
- 7 bar
- 20 bar
- 30 bar
- 70 bar
- 140 bar
- 200 bar
- 300 bar
- 700 bar
- 1,000 bar
The exact available range and pressure type depend on the selected model.
This broad range selection enables the XP2i to cover applications from low pneumatic pressures to very high hydraulic pressures.
Fully Temperature Compensated
A major advantage of the AMETEK Crystal XP2i is its active digital temperature compensation.
The instrument maintains its specified measurement accuracy from:
-10 °C to +50 °C.
No additional temperature accuracy term is required within this compensated range.
This is especially important for field calibration.
A pressure gauge may be calibrated under controlled laboratory conditions but subsequently used outdoors, in production facilities or in process environments where the ambient temperature differs significantly.
The XP2i is designed to maintain consistent measurement performance under these changing conditions.
Intrinsically Safe Pressure Measurement
The AMETEK Crystal XP2i is designed for pressure measurement in hazardous areas.
AMETEK lists intrinsic safety approvals including:
- ATEX
- IECEx
- CSA
This makes the XP2i particularly suitable for industries such as:
- Oil and gas
- Petrochemical processing
- Natural gas distribution
- Refineries
- Chemical processing
- Energy production
The exact approval and permitted operating conditions must always be checked for the specific instrument configuration and hazardous-area application.
Marine-Grade Enclosure
The XP2i uses a rugged:
marine-grade enclosure.
The housing is designed to resist corrosion and withstand demanding industrial environments.
The instrument combines a rugged aluminum alloy case with sealing against dust and water intrusion.
Internal circuitry is mounted using shock-absorbing elastomer supports.
This construction helps protect the instrument against mechanical stress encountered during transport and field operation.
Long Battery Life
The AMETEK Crystal XP2i operates using:
3 AA batteries.
AMETEK specifies continuous operating time of up to approximately:
1,500 hours.
The use of standard batteries simplifies replacement during field work and eliminates dependence on a proprietary rechargeable battery pack.
Pressure Safety Valve Mode
The XP2i includes a dedicated:
PSV – Pressure Safety Valve mode.
This function is designed for testing pressure relief and safety valves.
During a pressure safety valve test, pressure is increased until the valve opens.
When the XP2i detects the resulting pressure drop, it captures and displays the maximum pressure reached immediately before the valve opened.
This value remains available for the technician to record.
The feature reduces the subjectivity associated with visually observing a rapidly changing analog pressure gauge.
Safety Valve Testing
The dedicated PSV function makes the AMETEK Crystal XP2i particularly useful for:
- Pressure safety valves
- Pressure relief valves
- Rupture-related pressure tests
- Pop-pressure testing
Because the maximum pressure is electronically captured, different technicians can obtain more consistent results than when attempting to observe the peak pressure manually.
Optional DataLoggerXP
The XP2i can be expanded with:
DataLoggerXP.
This option enables the gauge to record pressure measurements internally.
Data logging is particularly useful for:
- Hydrostatic testing
- Leak testing
- Pressure decay testing
- Pipeline testing
- Long-term pressure monitoring
- Safety valve testing
- Process troubleshooting
Recorded measurements can subsequently be transferred to a computer for further analysis and documentation.
Pressure Recording
With DataLoggerXP, the AMETEK Crystal XP2i can function as a portable pressure recorder.
This combines the advantages of an intrinsically safe digital pressure gauge with electronic data acquisition.
The resulting system can reduce the need for separate chart recorders in many applications.
Digital data can also simplify subsequent analysis and documentation.
Gauge Pressure Measurement
Gauge-pressure versions of the XP2i measure pressure relative to atmospheric pressure.
This configuration is suitable for most industrial pressure applications, including:
- Hydraulic systems
- Pneumatic systems
- Compressors
- Pumps
- Process pressure
- Pressure transmitter testing
- Pressure gauge calibration
Multiple ranges allow the instrument to be matched to the required operating pressure.
Absolute Pressure Versions
The AMETEK Crystal XP2i is also available in absolute-pressure configurations.
Absolute pressure is referenced to absolute vacuum rather than local atmospheric pressure.
AMETEK offers XP2i absolute-pressure models from low absolute pressure ranges through high-pressure applications.
Absolute pressure measurement is particularly useful for:
- Barometric applications
- Gas distribution
- Vacuum systems
- Process applications
- Research
- Absolute pressure transmitter calibration
Low Absolute Pressure Ranges
AMETEK expanded the XP2i family to include lower absolute-pressure ranges.
These include versions around:
1.1 bar absolute
as well as higher absolute-pressure models.
This enables the XP2i to be used for applications that require precise absolute pressure measurement close to atmospheric pressure.
Digital Replacement for Multiple Test Gauges
The reading-based accuracy specification is one of the most important advantages of the AMETEK Crystal XP2i.
AMETEK explains that one XP2i can replace several conventional test gauges.
A conventional:
0.1% FS
gauge has a fixed absolute error based on its full-scale range.
At lower pressures, that error represents an increasingly large percentage of the actual reading.
The standard XP2i instead provides:
±0.1% of reading
over the specified portion of its range.
This enables one wider-range instrument to maintain useful relative measurement performance over a much broader pressure range.
Calibration Applications
The AMETEK Crystal XP2i can be used as a pressure reference for suitable comparison measurements.
A typical calibration setup consists of:
Pressure Source → XP2i Reference + Device Under Test
The pressure source generates defined calibration points.
The XP2i indicates the reference pressure while the reading of the device under test is recorded and compared.
Typical devices under test include:
- Analog pressure gauges
- Digital pressure gauges
- Pressure transmitters
- Pressure transducers
- Pressure sensors
- Pressure switches
The measurement uncertainty of the complete system must always be considered when determining whether the XP2i is suitable as a reference for a particular calibration task.
Pneumatic Pressure Calibration
Lower-pressure XP2i models can be combined with pneumatic pressure generation equipment.
A portable system can consist of:
XP2i + Pneumatic Hand Pump + DUT
This provides a compact calibration setup for field applications.
Pressure can be generated manually while the XP2i provides the reference indication.
Hydraulic Pressure Calibration
Higher-pressure XP2i models can be combined with hydraulic pumps and pressure comparators.
This allows calibration and testing at pressures up to:
15,000 psi / 1,000 bar
when all components of the pressure system are appropriately rated.
The XP2i is therefore suitable for both pneumatic and hydraulic pressure measurement.
GaugeCalHP Combination
For high-pressure applications, the XP2i can be combined with the:
AMETEK Crystal GaugeCalHP
hydraulic pressure comparator.
GaugeCalHP systems can generate pressure up to:
15,000 psi.
Oil and water versions are available.
When combined with a suitable XP2i, this creates a portable high-pressure comparison system for calibrating pressure gauges.
Crystal Pressure Fittings
The XP2i can be integrated with:
CPF – Crystal Pressure Fittings.
These high-pressure fittings simplify connection of the gauge to pumps, comparators and devices under test.
Different adapter configurations allow the system to be matched to commonly used pressure connections.
NPT Pressure Connection
The standard ordering configuration uses an:
NPT
connection arrangement.
This configuration is particularly common in North American pressure systems.
Other adapter types are available for international applications.

A:
M20 × 1.5
pressure connection option is also available.
M20 × 1.5 is widely used on pressure calibration equipment and industrial pressure instruments.
This simplifies integration of the XP2i into existing laboratory systems.
Bottom and Rear Connections
The XP2i can be configured with different pressure connection positions.
The standard arrangement uses a:
bottom connection.
A:
rear pressure connection
is also available.
This can be useful for panel installation and specialized test setups.
Dual Display Option
An optional:
Dual Display
configuration is available.
This allows additional measurement information to be displayed simultaneously.
The dual-display option can improve readability in applications requiring more than one pressure representation or measurement parameter.
RS-232 Communication
The XP2i includes digital communication capability.
The sealed RS-232 connection allows communication with compatible software and accessories.
This can be used for:
- Instrument configuration
- Data transfer
- Data logging
- Calibration applications
