Fixed combustible, flammable and explosive gas explosive detector

Main: This price is for display only, the actual price is subject to the quotation

Fixed combustible, flammable and explosive gas explosive detectorChicheng Manufacturer (hereinafter referred to as the detector) is a fixed instrument that can continuously detect the concentration of flammable gases in the working environment.

The fixed flammable and explosive gas explosive detector detects gas concentration through natural diffusion and uses imported catalytic combustion sensors, which have excellent performanceThe sensitivity and excellent repeatability of the LED digital display are suitable for factory applications, which can display the concentration value of leaked gas in real time. Once the preset alarm point is reached, the sound and light alarm signal or exhaust system can be immediately activated; The standard 4-20mA signal can be directly connected to the factory DCS system, and the RS485 digital signal is connected to the factory upper computer; The instrument adopts embedded microcontroller technology, with simple operation, complete functions, high reliability, and overall performance at the domestic level.
