Product Overview:
Combustible Gas Detector JD819 is a standalone combustible gas detector with a measuring range of 0-100% LEL. It adopts semiconductor sensor and micro-processing control and sounds an alarm on the spot when an alarm goes off. It has the characteristics of high stability and small sensitivity drift. It is mainly used in places where flammable gas (such as liquefied petroleum gas, natural gas, biogas, etc.) may leak.
