Gas Detector KB-501AG
Product model：KB-501AG
The KB-501AG composite gas detector is a new type of multi-gas online gas detection instrument produced by our company.
Gas sensor main detection principles are: electrochemical, infrared, catalytic combustion, PID light ion and other principles of gas sensors, high-precision temperature and humidity sensors.
Combined with excellent SMD technology, it has good repeatability, long service life and easy operation.
Adapt to petroleum, chemical, tunnel, gas transmission and distribution, urban pipe corridor, biochemical medicine and other industries.* Multi-gas, high sensitivity, long life, low drift, etc., stable operation;
* Self-test function of sensor failure, replace sensor in time, safer;
* Powerful sound and light alarm function;
* High-definition color display, intuitive and clear;
* 3 LEDs indicate fault, primary alarm, secondary alarm and relay output function;
* Bus RS485 (RTU), network transmission (optional), three (four) wire system 4 ~ 20mA (optional), switch quantity: 3
* Infrared remote control adjustment method, the detector can be adjusted without opening the cover, safe and convenient;
* Use explosion-proof design, suitable for dangerous conditions 1 and 2 areas;
