- 0 °C
- 10 °C
- 20 °C
- 25 °C
- 50 °C
- 75 °C
- 100 °C
- 122 °C
The achievable minimum temperature depends on the ambient conditions.
For accurate calibration results, sufficient stabilization time must be allowed before recording measurements.
High Temperature Accuracy of ±0.25 °C
The Fluke Calibration 9102S provides excellent temperature accuracy for a compact portable dry block calibrator.
The manufacturer specifies:
±0.25 °C
This specification describes the temperature accuracy under the manufacturer’s defined operating conditions.
It must not be confused with temperature stability or the uncertainty stated on an individual calibration certificate.
For demanding comparison calibrations, a suitable external reference thermometer can be used.
The reference thermometer measures the actual temperature within the calibration well.
This allows the device under test to be compared directly with a traceable temperature reference.
The uncertainty of the complete calibration system must be evaluated according to the applicable calibration procedure.
Excellent Temperature Stability of ±0.05 °C
The Fluke Calibration 9102S provides excellent temperature stability.
The manufacturer specifies:
±0.05 °C
Temperature stability describes the variation of the calibration block temperature over time under defined conditions.
Stable temperature conditions are essential for reliable temperature sensor calibration.
The Fluke Calibration 9102S provides a controlled temperature environment suitable for routine calibration and verification procedures.
For demanding applications, the actual temperature stability should be considered when evaluating the measurement uncertainty.
Two Calibration Wells
The Fluke Calibration 9102S features two calibration wells.
Both wells have a nominal diameter of:
12.7 mm (1/2 inch)
The well depth is:
102 mm
The two-well design allows a reference thermometer and a device under test to be inserted simultaneously.
This makes the instrument particularly suitable for comparison calibration.
One well can accommodate the reference thermometer, while the second well accommodates the temperature sensor being calibrated.
The manufacturer specifies well-to-well uniformity of:
±0.2 °C
This specification applies when sensors of similar dimensions are inserted to equal depths.
For accurate calibration, the influence of sensor geometry, immersion depth and thermal contact must be considered.
Removable Calibration Inserts
The Fluke Calibration 9102S uses removable calibration inserts.
These allow the instrument to accommodate temperature sensors with different diameters.
Available insert diameters include:
| Insert Diameter | Imperial Size |
|---|---|
| 1.6 mm | 1/16 inch |
| 3.2 mm | 1/8 inch |
| 4.0 mm | 5/32 inch |
| 4.8 mm | 3/16 inch |
| 6.4 mm | 1/4 inch |
| 7.9 mm | 5/16 inch |
| 9.5 mm | 3/8 inch |
| 11.1 mm | 7/16 inch |
Blank inserts are also available.
The standard configuration includes inserts with diameters of:
4.8 mm and 6.4 mm
The appropriate insert should be selected according to the diameter of the temperature sensor.
A small clearance between the sensor and the insert improves thermal contact and reduces measurement errors.
Excessive clearance can increase temperature differences between the calibration block and the sensing element.
Fast Heating Performance
The Fluke Calibration 9102S provides efficient heating performance.
The manufacturer specifies a typical heating time of:
10 minutes from ambient temperature to 100 °C
This allows technicians to reach common calibration temperatures quickly.
Short heating times are particularly useful when performing multi-point calibration procedures.
The fast temperature response helps reduce waiting periods and improves calibration efficiency.
Actual heating times depend on ambient conditions, sensor loading and operating conditions.
Fast Cooling Performance
The Fluke Calibration 9102S also provides efficient cooling performance.
The manufacturer specifies a typical cooling time of:
10 minutes from ambient temperature to 0 °C
This is particularly useful for temperature sensor calibration below ambient temperature.
The integrated temperature control system allows the instrument to generate both heating and cooling conditions.
This eliminates the need for separate heating and cooling devices for many routine calibration applications.
Short Stabilization Time
The Fluke Calibration 9102S features a typical stabilization time of:
7 minutes
This describes the time required for the calibration block to stabilize under the manufacturer’s specified conditions.
The stabilization time of the device under test must also be considered.
Large sensors or sensors with slow thermal response may require additional time before reliable measurements can be recorded.
For demanding calibration procedures, temperature stabilization should be verified using a suitable reference thermometer.
Compact Portable Construction
The Fluke Calibration 9102S is designed for mobile temperature calibration.
Its dimensions are:
99 × 140 × 175 mm
The instrument weighs approximately:
1.8 kg
This makes it suitable for transportation between different measurement locations.
The compact design also requires very little space on a laboratory workbench.
The Fluke Calibration 9102S is particularly useful for technicians who need to calibrate temperature sensors directly at the installation site.
AC and 12 V DC Operation
The Fluke Calibration 9102S offers flexible power supply options.
The instrument can operate using:
94–234 V AC, 50/60 Hz
or:
12 V DC
The rated power consumption is approximately:
60 W
The 12 V DC capability provides additional flexibility for mobile applications.
This can be useful when the instrument is operated from a suitable external DC power source.
The power source must meet the manufacturer’s electrical requirements.
Calibration of RTDs and Pt100 Sensors
The Fluke Calibration 9102S is suitable for calibrating resistance temperature detectors.
Typical applications include:
- Pt100 calibration
- Pt1000 calibration
- Industrial RTD calibration
- Temperature probe verification
- Temperature indicator testing
The RTD sensor is inserted into a suitable calibration insert.
The dry block generates a controlled temperature that can be compared with the temperature indicated by the device under test.
For more demanding applications, an external reference thermometer can be used.
The Fluke Calibration 9102S provides the temperature source but does not directly measure the electrical resistance of the RTD.
A suitable thermometer readout or resistance measurement instrument is required.
Calibration of Thermocouples
The Fluke Calibration 9102S can also be used for thermocouple calibration.
Thermocouples are widely used in industrial temperature measurement.
The instrument provides a stable temperature environment for checking thermocouple measurement systems.
The thermocouple is inserted into the calibration block and allowed to stabilize.
Its indicated temperature can then be compared with the reference temperature.
For accurate thermocouple calibration, reference junction compensation and the measurement uncertainty of the readout must be considered.
Calibration of Digital Thermometers
The Fluke Calibration 9102S is suitable for checking digital thermometers.
Digital thermometers are commonly used in laboratories, industrial production and quality assurance.
The temperature sensor is inserted into a suitable calibration well.
The thermometer indication is then compared with the reference temperature.
This allows users to verify the measurement performance of the thermometer at several temperature points.
Calibration of Temperature Switches
The Fluke Calibration 9102S is also suitable for checking temperature switches.
Temperature switches are used to monitor and control industrial processes.
They activate or deactivate an electrical contact when a defined temperature is reached.
The Fluke Calibration 9102S provides a controlled temperature environment for checking switching points.
The temperature can be increased or decreased to determine the switching temperature.
An external instrument is required to detect the electrical switching signal.
The instrument can also be used to investigate switching hysteresis.
RS-232 Interface
The Fluke Calibration 9102S includes an RS-232 communication interface.
This interface allows the instrument to communicate with compatible external equipment.
RS-232 communication can be used for remote operation and integration into suitable calibration systems.
This is particularly useful for laboratories and industrial users who want to incorporate the dry block calibrator into automated or computer-assisted calibration procedures.
The available communication commands and interface settings are described in the manufacturer’s operating instructions.
No Calibration Liquid Required
Unlike liquid calibration baths, the Fluke Calibration 9102S does not require a calibration fluid.
The instrument uses a solid metal block to transfer heat to the temperature sensors.
This provides several practical advantages:
- No calibration liquid required
- No filling or draining procedures
- No risk of calibration fluid leakage
- Reduced cleaning requirements
- Convenient transportation
- Fast preparation for calibration work
These advantages make the Fluke Calibration 9102S particularly suitable for field calibration and mobile maintenance applications.
