Product detail:
NZ03 fixed O2 gas alarm 0086 15037127860
Introduction:
NZ03 wall mounted single gas detector is mainly used in industrial environment. It adopts
advanced electrochemical sensor of high accuracy and good linearity. It's easy to connect with
other instruments and controllers because it has a 4~20mA current signal.The alarm output can
connect with a fan or other alarm device.
It can work in harsh environment and has dust-proof,damp-proof and other advantages. It
widely used in underground pipeline, mine, oil field and other places to rescue the combustible
gas and toxic gas from leakage and protect personal safety and equipment safety effectively.
