Product Details
KSF6-O2-202 Gas Detector
Product Introduction
The KSF6-O2-202 gas detector is a device that can monitor in real
time the concentrations of sulfur hexafluoride (SF6) and oxygen in
the air, as well as the environmental temperature and humidity in
the working places of indoor electrical equipment. It gives early
warnings according to the set alarm values. The instrument has a
human body infrared monitoring function and can upload real-time
detection data online through RS485 communication and WIFI
communication functions. It is widely used in fields such as the
gas analysis industry, industrial process control, environmental
detection, and power plants and substations.
