Precision Testing for Widely Used 302 Series Detectors

The HST-B-BLO Series Heat Detector Test Kit provides a practical, portable solution for testing Thermotech® 302 Series detectors and their widely used equivalents. Featuring a narrow 7/32 inch chamber and two pre-set test temperatures (135°F and 194°F), it ensures quick, non-destructive field testing aligned with manufacturer guidance.

These models support compatibility across major detector brands, including Siemens®, Fire-Lite®, GE®, KFCi, and Edwards®. As with all HST Series units, both standard and rate-controlled heating versions are available to suit different application needs. Made and assembled in the USA using a combination of domestic and imported components.
