Gas alarm and transmitter

Author:admin | Add Time: 08-04-10

gas alarm and transmitter ( Fixed installation)

Adopt Imported electrochemical or catalytic combustion gas sensor, has the advantage of stable performance, high accuracy and good linearity, strong anti-jamming and long life. Detection probe and host combined, on-site detection, alarm, control, and continuous work. Alarm levels in the range is adjustable, sound and light alarm simultaneously. Diffusion test method, four digital tube display the measured values, control contact output, alarm linkage contact when equipment can access DCS system, choose a different sensor can measure different gases.
