Portable Temperature Calibrators

Product Details

Our Portable Temperature Calibrators are highly accurate dry well temperature standards designed for testing and calibrating thermometers, temperature sensors, thermocouples, RTDs, and temperature switches. The dry well design and precision adapter chucks provide excellent heat transfer into the device under test and fast heating and cool-down times.

These calibrators are suitable for applications outside the lab where variable environmental conditions exist. Each dry well calibrators is designed for a specific temperature reference range; sub-ambient/low temp (-40F – 250F), mid temp (95F – 662F), and high temp (100F – 1200 F).
