Features :
SPD202combustible gas detector can be used in hazardous areas indoors and outdoors, where combustible gas is produced, stored, used, etc., such as chemical,petroleum, metallurgy, oil depot,LPG (Liquefied Petroleum Gas) station , pharmaceutical, gas transmission and distribution, etc. to detect the leakage and show the leaking concentration with a digital display. This device can set two-level alarming value. The detector can raise the acousto-optic alarming when the detected concentration reaches the preset value
