Series 302 heat detectors are designed for use in normal environments as well as environments where the detectors are subject to weather, moisture (internal condensation), and explosive atmospheres. They are normally-open devices designed to close an electrical circuit upon activation. All models feature rate compensation. The 302-EPM-194 is available with a 194°F (90°C) fixed temperature rating. It is an explosion proof detector with hexagonal grip bushing with 1/2" conduit threads for attachment to threaded hub covers of series JL fixture fitting manufactured by Killark ...

The Triplett Model DPR302 Differential Pressure Manometer measure gauge and differential pressure to ±2psi. Use one input to measure the gauge pressure of a single source. Use both inputs to measure the differential pressure between two points of a single source or between 2 sources revealing which input has the higher pressure and the difference between them. Measurements are viewed on the large backlit LCD display in 11 units of measure. Min/Max/AVG records highest, lowest and average readings with relative time stamp. Data Hold momentarily freezes the displayed reading for easy ...
