Product Description
Fixed Combustible Gas Detector Overview
This advanced fixed-type combustible gas detector utilizes catalytic or infrared sensors to convert gas concentrations into digital signals. Designed for integration with gas control systems, it provides reliable monitoring in refineries, chemical plants, LPG stations, boiler rooms, painting facilities, and other industrial environments where combustible gases may be present.

Working Principle
Catalytic combustion-type detectors measure combustible gas concentrations through resistance changes in heated platinum wire. When combustible gases enter the detector, they undergo flameless combustion on the platinum surface, generating heat that alters the wire's resistance. This resistance change is precisely measured to determine gas concentration levels.
Key Features & Benefits
- Extended lifespan with high accuracy and sensitivity
