- 100 °C
- 150 °C
- 200 °C
- 250 °C
- 300 °C
- 375 °C
The temperature can be adjusted directly using the front-panel controls.
The integrated temperature controller regulates the heating block to the selected setpoint.
For demanding calibration applications, sufficient stabilization time must be allowed before recording measurement results.
High Temperature Accuracy
The Fluke Calibration 9100S provides reliable temperature accuracy across its operating range.
The manufacturer specifies the following accuracy values:
| Temperature | Accuracy |
|---|---|
| 50 °C | ±0.25 °C |
| 100 °C | ±0.25 °C |
| 375 °C | ±0.5 °C |
These values describe the manufacturer’s specified temperature accuracy under defined operating conditions.
They should not be confused with the temperature stability specification or the calibration uncertainty stated on an individual calibration certificate.
For demanding comparison calibrations, an external reference thermometer can be used to measure the actual temperature of the calibration block.
The uncertainty of the complete measurement system must be considered when evaluating calibration results.
Excellent Temperature Stability
The Fluke Calibration 9100S provides stable temperature conditions for sensor calibration.
The manufacturer specifies:
| Temperature | Temperature Stability |
|---|---|
| 50 °C | ±0.07 °C |
| 100 °C | ±0.1 °C |
| 375 °C | ±0.3 °C |
Temperature stability describes the variation of the calibration block temperature over time under specified conditions.
Stable temperature conditions are essential for obtaining reliable calibration results.
When several temperature sensors are calibrated simultaneously, sufficient stabilization is particularly important.
The actual measurement uncertainty depends on the temperature stability, temperature uniformity, reference thermometer and device under test.
Fast Heating Performance
One of the main advantages of the Fluke Calibration 9100S is its fast heating performance.
The manufacturer specifies a typical heating time of:
9.5 minutes from 35 °C to 375 °C
This allows technicians to reach high calibration temperatures quickly.
Short heating times are particularly useful when performing multi-point calibration procedures.
The fast temperature response helps reduce waiting times and improves calibration efficiency.
Actual heating times may depend on ambient conditions, sensor loading and operating conditions.
Efficient Cooling Performance
The Fluke Calibration 9100S also provides efficient cooling performance.
The manufacturer specifies a typical cooling time of:
14 minutes from 375 °C to 100 °C
This allows technicians to perform calibration procedures involving both increasing and decreasing temperature sequences.
Cooling times depend on the initial temperature, ambient conditions and thermal loading.
The instrument should always be allowed to cool sufficiently before transportation or storage.
Short Stabilization Time
The Fluke Calibration 9100S features a typical stabilization time of:
5 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 Handheld Construction
The Fluke Calibration 9100S is one of the most compact dry block calibrators available for industrial temperature calibration.
Its dimensions are:
57 × 125 × 150 mm
The instrument weighs approximately:
1 kg
This makes it particularly suitable for mobile calibration applications.
The compact design allows technicians to transport the instrument easily between different measurement locations.
It also requires very little space on a workbench.
The Fluke Calibration 9100S is therefore an excellent solution for service technicians who need to calibrate temperature sensors directly at the installation site.
Multiple Calibration Wells
The Fluke Calibration 9100S features an integrated metal calibration block with several sensor wells.
Different configurations are available to accommodate temperature sensors with different diameters.
The standard well depth is:
102 mm
The smallest 1.6 mm well has a depth of:
89 mm
The appropriate well configuration should be selected according to the diameter of the temperature sensors being calibrated.
Good thermal contact between the sensor and the calibration well is essential for minimizing measurement errors.
The sensor should be inserted sufficiently deeply to reduce heat conduction effects along the probe stem.
Different Model Configurations
The Fluke Calibration 9100S is available in several configurations.
Fluke Calibration 9100S-A
The 9100S-A is a handheld dry block calibrator with well configuration A.
Fluke Calibration 9100S-B
The 9100S-B provides an alternative calibration well configuration.
Fluke Calibration 9100S-C
The 9100S-C is designed for applications requiring another combination of sensor well diameters.
Fluke Calibration 9100S-D
The 9100S-D provides an additional calibration well configuration.
The appropriate version should be selected according to the dimensions of the temperature sensors being calibrated.
Unlike dry block calibrators with removable inserts, the Fluke Calibration 9100S uses fixed calibration wells.
The well configuration is therefore an important consideration when ordering.
Calibration of RTDs and Pt100 Sensors
The Fluke Calibration 9100S 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 well.
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 9100S 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 9100S can also be used for thermocouple calibration.
Thermocouples are widely used in industrial applications requiring elevated temperatures.
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 Bimetal Thermometers
The Fluke Calibration 9100S is suitable for checking small bimetal thermometers.
Bimetal thermometers are commonly used in industrial heating systems, machinery and process equipment.
The sensing element is inserted into a suitable calibration well.
The indicated temperature can then be compared with the temperature generated by the calibration block.
The compact design of the Fluke Calibration 9100S makes it particularly useful for routine verification of mechanical temperature indicators.
RS-232 Interface
The Fluke Calibration 9100S 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.
Simple Front-Panel Operation
The Fluke Calibration 9100S is designed for straightforward operation.
The temperature setpoint can be entered using the front-panel buttons.
The digital display provides information about the temperature.
The instrument features a display resolution of:
0.1 °C
This makes it easy to set and monitor calibration temperatures.
The simple operating concept reduces training requirements and allows technicians to begin calibration work quickly.
No Calibration Liquid Required
Unlike liquid calibration baths, the Fluke Calibration 9100S 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.
There is no need to fill or drain calibration liquid.
The risk of fluid leakage during transportation is eliminated.
Cleaning and maintenance requirements are reduced.
The instrument can be prepared for use quickly.
These advantages make the Fluke Calibration 9100S particularly suitable for field calibration and mobile maintenance applications.
