Edwards Signaling, 302-ET-135, All-Weather Heat Detector - Vertical, Box Mount 1/2" Npt, FM

The NGD269 is ideal for checking automotive exhaust and fuel systems, liquid- and gas-fired heating systems, propane tanks and filling stations, cracked heat exchangers and manholes/sewers. Detects the presence of most combustible gases without measuring or displaying their concentration. The unit's analog bar graph, and the speed and tone of its audible alarm, enable the NGD269 to pinpoint the location of a gas leak by comparing its responses to gas exposure at different points. Measures and displays the concentration of CH4 (methane/natural gas), C3H8 (propane) and H2 (hydrogen) for ...

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 ...

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-AW-194 is available with a 194°F (90°C) fixed temperature rating. It is an all-weather heat detector designed for moisture proof or dust proof installations. Requires no special back box when the all-weather leads are properly spliced to "THW" or ...

The Triplett Model GSM100 Combustible Gas Detector identifies the presence of combustible gases such as Methane, Hydrogen, Carbon Monoxide, Propane, Ethylene, Ethane, Hexane, Benzene, Iso-Butane, Ethanol, Acetaldehyde, Formaldehyde, Toluene, P-Xylene, Ammonia, and Hydrogen Sulfide. It will also detect common mixtures that would include or emit more than one of these gases: Natural Gas (typically consists of a high percentage of methane and smaller percentages of propane and other gases), Paint Thinners, Industrial Solvents, Dry Cleaning Fluids, and Gasoline. The GSM100 has a 16" (406mm) ...

SuperDuct is slim feature-rich alternative to bulky duct smoke detectors. Designed for easy installation and superb reliability. SuperDuct represents the perfect balance of practical design and advanced technology. SuperDuct detectors feature a unique design that speeds installation and simplifies maintenance. Removable dust filters, conformally coated circuit boards, and optional water-resistant gaskets keep contaminants away from components, ensuring years of trouble-free service. When cleaning is required, the assemblies come apart easily and snap back together in seconds. SuperDuct ...
