Wholesale of gas detectors

Product Name:TVOC gas detector

Product model: DS800-TVOC-PID

Product Introduction:

DS800 typeTVOC gas detectorAdopting imported PID photoionization sensors, with fast response time and high measurement accuracy. It is compatible with multiple signal outputs such as 4-20mA and RS485, and can be connected to platforms such as PLD and DCS for remote transmission. No back cover design to prevent the detector from being affected by external environment. Infrared remote control operation, no on-site cover opening process, safe and convenient.

Application fields:Suitable for explosion prevention, toxic gas leakage rescue, underground pipe props, mines, metallurgical power plants, tunnels, tunnels and other places, effectively preventing poisoning accidents, ensuring the safety of workers' lives is not harmed, and production equipment is not damaged.
