The Det-Tronics hydrogen sulfide gas detector delivers fast and repeatable H2S detection in extreme temperature and humidity applications where electrochemical sensing technologies are not preferred. The NTMOS (NanoTechnology MOS) H2S sensor uses the latest nanotechnology to ensure accuracy, reliability, and repeatability. The sensing element is packaged in a rugged housing and protected by a sintered stainless steel flame arrestor, making it suitable for installation in Class I, Division 1 locations. + Detects H2S faster and more accurately than traditional Metal Oxide Sensors (MOS). + Can be installed as a stand-alone sensor or combined with a display for local indication. + Performs reliably in extreme climates with accurate and consistent operation proven through performance testing to the ISA-92.0.01 standard.
