NZ03 wall mounted combustible/flammable gas leak detector/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.
