Product Introduction
The detector uses imported sensors and features long-term stability, short response time, and strong anti-interference capability.
The detector uses diffusion sampling, converting the weak signal output by the sensor into a digital signal and uploading it to a combustible gas alarm controller or PLC and other equipment.
The detector, together with a combustible gas alarm controller or PLC, forms an alarm control system.
