Combustible Gas Leak Detector

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 ...

The 55800 leak detector employs a new metal oxide gas sensor for the detection of chlorofluorocarbon gasses and blends. This tin oxide sensor is characterized by high sensitivity and fast response, upon detecting the presence of extremely small levels of chlorofluorocarbon gases. Integrated into the design is a powerful microprocessor that automatically selects the best-operating conditions for the sensor, to ensure optimum performance. The optimum sensor performance is maintained and monitored throughout the life of the sensor. LCD Features: WAIT: This indication flashes whenever the ...
