New challenges require new tools.  TEGAM has rethought thermocouple calibrators to offer you the performance you need today without complicating your work. The new 940 Series provides laboratory grade calibrations in a highly portable package that goes to the worksite with ease. Industries that measure temperature are being pushed to achieve better results for both quality and product safety. TEGAM has responded by designing an instrument that leads its class in terms of accuracy, battery life, convenience and ease of use.

TEGAM Temperature Calibrators for Your Industry

Perform on site calibration and verification of thermocouples, temperature transmitters, indicators, process controllers and displays with lab grade accuracy in the varied conditions found on the plant floor.

  • Aerospace: verify engine temperature sensing and displays, heating/ventilation, climate control, heat treating AMS2750 oven controls and surveys, composite repair temperature controllers and fire detection systems.
  • Food Industry: Ovens, freezers, warehousing and refrigeration are verified for correct storage temperature and final cooking temperatures. Validate sensors, controllers and displays with accuracy and ease.
  • Automotive: verify engine coolant and oil temperature sensing, calibrate ECU inputs, climate control, battery temperature monitoring systems and heat-treating ovens.
  • Plastics: validate heaters and controllers, liquid cooling loops and process automation temperature inputs
  • Chemical Plants: verify thermocouples and calibrate temperature transmitters, validate process controller inputs.
