europascal EP-P40 is a versatile handheld pneumatic pressure test pump for generating vacuum and positive pressure during professional calibration, testing and adjustment of pressure measuring instruments. With a pressure range from approximately -0.95 bar to 40 bar / 580 psi, the compact EP-P40 covers a broad range of pneumatic calibration applications in the laboratory, workshop and field.
The europascal EP-P40 is designed for comparison calibration. A suitable reference pressure gauge is connected to the reference port, while the device under test is connected to the second pressure connection. The pump then generates the same pneumatic pressure for both instruments, allowing their indications to be compared directly.
Unlike a pressure calibrator or digital pressure gauge, the EP-P40 does not independently determine the reference pressure. Its primary function is to generate, adjust and release pneumatic pressure. The measurement accuracy of a complete calibration setup is therefore determined primarily by the connected reference instrument and the measurement uncertainty of the complete system.
With its compact handheld construction, approximately 1.7 kg weight, integrated fine-pressure adjustment and pressure generation up to 40 bar, the EP-P40 provides a practical solution for technicians who require a portable pneumatic pressure source.
At europascal, the EP-P40 can be combined with suitable digital reference pressure gauges and calibration equipment to create complete pressure calibration systems. For professional calibration and metrological traceability, visit the europascal Calibration Service.

Pressure Range from -0.95 to 40 bar
The europascal EP-P40 provides pneumatic pressure generation across a broad range:
-0.95 bar to 40 bar
or up to approximately:
580 psi.
This combination of vacuum and positive pressure makes the EP-P40 suitable for many common industrial pressure calibration tasks.
One portable pressure source can therefore be used for both vacuum and positive gauge pressure applications.
Pneumatic Pressure Generation
The europascal EP-P40 uses:
air
as its pressure medium.
This provides an important advantage when calibrating pressure instruments that should not come into contact with hydraulic oil or water.
Pneumatic operation is particularly suitable for:
- Pressure gauges
- Digital pressure gauges
- Pressure transmitters
- Pressure sensors
- Pressure transducers
- Pressure switches
Because no hydraulic fluid is required, setup and cleaning are simplified compared with hydraulic pressure pumps.
Pressure Generation up to 40 bar
Despite its compact handheld construction, the europascal EP-P40 can generate pneumatic pressure up to:
40 bar / 580 psi.
This makes it suitable for applications that exceed the pressure capability of many conventional pneumatic hand pumps.
The operator can manually generate the required pressure and then use the integrated fine adjustment to approach the desired calibration point.
Vacuum Generation
In addition to positive pressure, the europascal EP-P40 can generate vacuum down to approximately:
-0.95 bar.
This corresponds to approximately 95% vacuum relative to atmospheric pressure under suitable conditions.
Vacuum capability is useful when testing:
- Vacuum gauges
- Compound pressure gauges
- Vacuum transmitters
- Pressure sensors
- Pressure switches
- Negative gauge pressure instruments
The combination of vacuum and positive pressure significantly increases the versatility of the pump.
Fine Pressure Adjustment
Generating pressure is only one part of a professional comparison calibration.
The required calibration points must also be approached precisely and maintained sufficiently stable for the reference and DUT readings to be compared.
The europascal EP-P40 therefore incorporates a fine pressure adjustment mechanism.
Fine adjustment capability down to approximately:
0.1 mbar
allows the operator to make very small pressure corrections.
This is particularly useful when approaching a defined calibration point after the main pressure has been generated with the hand pump.
Comparison Calibration
The europascal EP-P40 is particularly suitable for:
comparison pressure calibration.
The basic principle is straightforward.
A reference pressure gauge and the device under test are connected to the same pneumatic pressure system.
The EP-P40 generates the pressure.
A typical setup is:
europascal EP-P40 → Reference Pressure Gauge + Device Under Test
Both pressure instruments are exposed to the same generated pressure.
The indication of the DUT can then be compared with the reference value.
EP-P40 as Pressure Generator
It is important to distinguish between pressure generation and pressure measurement.
The:
europascal EP-P40 generates pressure.
The:
reference pressure gauge measures pressure.
The:
device under test is compared with the reference.
The EP-P40 itself therefore does not determine the measurement uncertainty of the reference pressure.
For professional calibration, the selected reference instrument must provide suitable accuracy, stability, resolution and calibration traceability.
Reference Pressure Gauge Connection
The europascal EP-P40 provides a dedicated connection for the reference pressure gauge.
The reference port uses a:
G1/4″ connection.
A suitable digital pressure gauge or pressure calibrator can therefore be connected directly or through an appropriate adapter.
The reference instrument should be selected according to the required pressure range and calibration uncertainty.
Device Under Test Connection
The device under test is connected to the second pressure connection.
This allows the reference instrument and DUT to experience the same pressure simultaneously.
The test connection is also based on a:
G1/4″ connection.
Different thread types can be accommodated using suitable adapters.
Hand-Tight Connections
The pressure connection concept is designed for convenient field use.
Compatible pressure gauges can be connected using hand-tight connectors.
This reduces setup time when several devices must be tested or calibrated consecutively.
It can also reduce the need for additional tools during routine calibration work.
Adapter Set
Different pressure instruments use different mechanical pressure connections.
For this reason, the europascal EP-P40 can be supplied with adapters for common pressure threads.
Available connection sizes include:
- G1/8″
- G1/4″
- G3/8″
- G1/2″
- 1/8″ NPT
- 1/4″ NPT
- 1/2″ NPT
- M12 × 1.5
- M20 × 1.5
This allows a broad range of industrial pressure instruments to be connected to the pump.
Pressure Gauge Calibration
A typical application for the europascal EP-P40 is pressure gauge calibration.
The reference gauge and pressure gauge under test are connected to the pump.
The operator then generates a sequence of defined pressure points.
For example, a calibration can include:
0% → 20% → 40% → 60% → 80% → 100%
of the selected calibration range.
The sequence can then be repeated in decreasing pressure.
This allows the pressure gauge indication to be evaluated across its measurement range.
Depending on the calibration procedure, increasing and decreasing measurements can also provide information about hysteresis.
Digital Pressure Gauge Testing
The EP-P40 can also be used for comparison testing of digital pressure gauges.
A higher-accuracy digital reference gauge is connected to the reference port.
The digital gauge under test is connected to the DUT port.
The generated pressure is then compared at defined measurement points.
This creates a compact calibration setup without requiring an electrically driven pressure controller.
Pressure Transmitter Calibration
The europascal EP-P40 is also suitable as a pressure source for transmitter calibration.
A typical pressure transmitter calibration system consists of:
EP-P40 + Reference Pressure Gauge + Electrical Calibrator + Pressure Transmitter
The EP-P40 generates the pneumatic pressure.
The reference instrument measures the actual pressure.
An electrical calibrator measures the output of the pressure transmitter.
For a conventional industrial transmitter, this may be a:
4 to 20 mA
signal.
The transmitter input and output can therefore be compared over the complete calibration range.
Pressure Sensor Calibration
Pressure sensors and transducers can be tested using the same principle.
The EP-P40 generates the required pneumatic pressure while a suitable reference instrument measures the actual applied pressure.
The electrical output signal of the sensor can then be recorded at each calibration point.
Depending on the sensor, this output may be:
- Current
- Voltage
- Frequency
- Digital signal
The EP-P40 remains the pneumatic pressure source within the calibration system.
Pressure Switch Testing
The europascal EP-P40 is also useful for pressure switch testing.
Pressure is increased gradually until the switch changes state.
The corresponding pressure is read from the connected reference instrument.
The pressure can then be reduced until the switch returns to its original state.
This enables determination of:
- Switching pressure
- Reset pressure
- Switching hysteresis
The integrated fine adjustment is particularly useful when approaching the switching point.
Portable Field Calibration
The compact dimensions and approximately:
1.7 kg
weight make the EP-P40 particularly suitable for portable applications.
Instead of removing every pressure instrument and transporting it to a calibration laboratory, suitable instruments can be tested directly at their installation location.
This can reduce downtime and simplify maintenance procedures.
Laboratory Applications
The europascal EP-P40 is equally suitable for laboratory use.
Combined with a calibrated reference pressure gauge, it provides a straightforward manual comparison system for routine pneumatic pressure calibration.
Because pressure is generated manually, no electrical power supply or compressed-air source is required for the basic pump operation.
This makes the system flexible and easy to install on a calibration bench.
Clean Pneumatic Operation
An important advantage of the EP-P40 is its pneumatic operating principle.
Unlike hydraulic pressure pumps, the EP-P40 does not require oil or water for normal pressure generation.
This makes it particularly suitable for devices that must remain free from hydraulic contamination.
Clean pneumatic operation also simplifies changing between different devices under test.
No External Pressure Supply Required
The europascal EP-P40 generates pressure manually.
An external compressed-air cylinder or electrically powered compressor is therefore not required for basic operation.
This is especially advantageous for mobile service applications.
The technician can take the pump, reference gauge and adapters directly to the measurement location.
Complete Portable Calibration Set
The EP-P40 can be configured as a complete portable pressure test set.
A practical system can include:
- europascal EP-P40
- Reference pressure gauge
- Pressure hose
- Connection adapters
- Seals
- Carrying case
This creates a compact solution for routine field pressure calibration.

EP-P40 vs. Digital Pressure Gauge
The europascal EP-P40 should not be confused with a digital pressure gauge.
A digital pressure gauge:
measures pressure.
The EP-P40:
generates and adjusts pressure.
Both instruments can be combined to form a complete manual calibration system.
For example:
EP-P40 + Precision Digital Pressure Gauge = Portable Pressure Calibration System
The accuracy of this system depends primarily on the selected reference pressure gauge and the complete measurement uncertainty budget.
EP-P40 vs. Hydraulic Pressure Pump
The EP-P40 is a:
pneumatic pressure pump.
This means that air is used as the pressure medium.
Pneumatic systems provide clean operation and are particularly convenient at low and medium pressures.
Hydraulic pressure pumps use a liquid such as oil or water and are typically preferred when substantially higher pressures must be generated.
With a maximum pressure of 40 bar, the EP-P40 covers a particularly useful range for pneumatic pressure calibration.
