9011 High-Accuracy Dual-Well Calibrator





9011 High-Accuracy Dual-Well Calibrator

The 9011 features two independently controlled temperature wells, which make calibrating RTDs and thermocouples faster than ever. While readings are being taken at one temperature, the other well can be ramping up or down to the next point. Checking the zero and span points of temperature transmitters is a breeze. The cold block can even be used as a zero-point reference for a thermocouple making measurements in the hot block.

The 9011 is a high-accuracy unit that is capable of laboratory as well as field calibrations. Stabilities to ±0.02 °C are possible, and display accuracy is better than ±0.25 °C. Using multi-hole interchangeable inserts, you can calibrate more probes at the same time. With a single RS-232 port for both wells, you can automate your calibration work and be even more efficient. Add on Fluke Calibration’s 9938 MET/TEMP II software and totally automate your calibrations of RTDs, thermocouples, and thermistors.

Every dry-well we ship from the factory includes a full NIST-traceable calibration report with test data for each well at each point. There’s no extra charge for the report or the test readings from your unit. We also include your choice of multi-hole inserts. If you don’t find one that suits your applications, we’ll provide a blank sleeve or have a custom one made.


Widest temperature range available in a single dry-well

  • Combined range from –30 °C to 670 °C, one unit – two blocks
  • Two independent temperature controllers (hot and cold side)
  • Stability to ±0.02 °C
  • Multi-hole wells for calibrating up to eight probes simultaneously

To give you the widest temperature range available in a dry-well calibrator, we’ve combined two of our most popular units. The 9011 allows temperature probes to be calibrated from –30 °C to 670 °C in a single unit.
