PORTABLE ENGiNE TEST SETS & TRIMMERS Multi-Range Thermocouple and Thermal Switch Tester H394R NSN 4920-01-468-9406 H394-115 NSN 4920-01-464-9810 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. 1 TEMPCAL® is a registered trademark of Howell Instruments, Inc. 2 Chromel® and Alumel® are registered trademarks of Hoskins Manufacturing Company .^8945 South Freeway Fort Worth, Texas 76140 www.howellinst.com 817-336-7411 Fax: 817-336-7874 info@howellinst.com
