Fixed Combustible Gas Detector
Fixed LPG Gas Leak Detector Combustible Gas Detector with Explosion-Proof Alarm lamp
Overview
The fixed gas detector is an advanced industrial safety device designed to monitor gas concentrations in hazardous environments. It employs high-quality catalytic or electrochemical sensors (from leading brands) to accurately detect flammable or toxic gases and convert the gas density into a standard 4–20mA analog signal or digital output (RS485) for integration with control systems.
Key Applications
Widely used in refineries, chemical plants, LPG stations, boiler rooms, painting facilities, petroleum, metallurgy, pharmaceuticals, gas transportation, and wastewater treatment plants—anywhere gas leaks pose a risk.
Detect Gas: O2, Combustible Gas, CO, H2S, NH3, H2, Cl2, HCl, SO2, NO, NO2, CO2, C2H4O, C2H6O, CH3OH/ CH4O, HCHO/ CH2O, HCOOH, C2H3Cl, C4H8, VOC, O3, PH3, HCN.
