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