The sulfur dioxide detection alarm used in industrial sites can be divided into fixed sulfur dioxide detector and handheld portable sulfur dioxide detection alarm.
fixed sulfur dioxide detection alarm is divided into two types: multi-wire system and bus system.
It is composed of two parts: sulfur dioxide transmitter/probe and gas alarm control host, and the multi-wire host can be divided into single-channel, double-channel, four-channel and eight-channel. (Each channel means one sulfur dioxide probe can be attached)
The site can be equipped with a digital display of sulfur dioxide detection probe or imported sulfur dioxide detection probe.
