Online Toxic Gas Detector KB-501SG
Gas detector KB-501SG is a new type toxic gas detector which used advanced electrochemical sensor and microcontroller, employed sophisticated SMD technology. It has following advantages: good repeatability,high resistance to humidity-temperature jamming, long performance life and simple operation. It is applied to inspection for toxic gas concentration in industrial environments.
KB-501SG can translate the appointed gas concentration signals into digital signals display. Three-wire system 4~20mA electric current signals output, with long-distance transmission and high anti-interference capacity. In addition, it has two-stage alarm function with acoustic and light signals.
Common applications is gas safety inspection and alert for industrial scene, such as petroleum refinery, chemical plants, LPG stations, boiler rooms, gas stations, paint spray booths, etc.
