Oil and gas concentration detector

Product Overview
This detector is a 4-20mA current loop output gas alarm, which uses hardware modulation and signal conditioning methods to ensure stable operation,

Reliable; The sensor adopts imported catalytic combustion sensors and electrochemical sensors; Sensors can collect various combustible gases

Harmful gases can be widely used in chemical enterprises, gas production enterprises, as well as toxic and harmful substances such as steel mills and power plants

Detection occasions.
This product has no display and supports sound and light alarm (optional sound and light alarm for on-site sound and light alarm), with stable performance

High cost-effectiveness, supports 24V or 220V power supply, can be connected to PLC for closed-loop control;
