Wireless Transmission Solar Charging Wall Mount Fixed Combustible
Gas Detector
K900 fixed gas detection transmitter can be widely used in metallurgy, petroleum, petrochemical, chemical, shipbuilding and other industries. The instrument
adopts explosion-proof design,(4 ~ 20) MA standard signal output, which can be transmitted
remotely and directly into DCS system. The detection sensor has the
characteristics of high sensitivity, rapid response, long service
life and short polarization time, and is at the leading level of
similar products in China.
