Additel 875 Series Dry Well Calibrator

The Additel 875-155 Dry Well Calibrator

Designed with a patented heat pipe technology that has drastically reduced the amount of time it takes the calibrator to move from one temperature to the next. This new and innovative technology isn't just fast, but it also reduces the number to thermo-electric modules required to reach temperatures as low as -40°C.  In turn, the ADT875 is highly dependable and requires fewer active parts and valuable time to get the job done.


  • Temperature range from -40°C to 155°C 
  • Portable and quick to temperature
  • Metrology-level performance in stability, uniformity, accuracy and loading effect
  • Dual-zone control
  • Self-calibration feature
  • Process calibrator option provides a multi-channel readout for a reference thermometer, RTD's and TC's, task documentation and HART Communication

The Additel model ADT875-155 can move from ambient to -40°C in under 20 minutes!  It can also move from -40°C back to room temperature in 5 minutes or less!
