AS-525 Combustible Gas Detector
Category:
AS-525 intelligent combustible gas detector adopts catalytic combustion principle technology to detect the concentration of various combustible gases in the ambient air, which can convert the gas concentration monitored on site into standard 4-20mA signal output or RS485 output. It is a standard intelligent three- wire combustible gas detector that is suitable for factory applications such as LCD field display, and sensor replacement (plug and play) . It meets the requirements of industrial site safety monitoring for equipment reliability and diversification of gas measured.
