Multi-Range Thermocouple and Thermal Switch Tester Precision Testing for • Thermal Switches • Chromel®-Alumel®2 Thermocouples • Continuous-Wire Fire Detection Systems Howell’s TEMPCAL® Tester provides a portable, lightweight means for conducting repeatable, accurate testing of thermal switches, thermocouples and continuous-wire fire detection systems. Connected to the H394, TEMPCAL® Heater Probes can test heat sensitive detectors either in their normal operating location or on the bench. Testing thermal sensors in place dramatically reduces test time and associated cost. Providing rapid heat rise and stabilization, this system enables an 800 °F thermal switch to be heated to test temperature in approximately five minutes. The five minute period is sufficient to heat the thermal switch and verify its operation. Once the probe is heated, additional switches can be checked rapidly.
