VTSYIQI NOX Gas Detector Fixed Nitrogen Oxide Gas Leak Alarm Monitor Meter Tester with Aluminum Shell Material Measuring Range from 0 to 20ppm Free Contact Output Resolution 0.1ppm for Gas Test of Refinery Chemical Plant Boiler Room

VTSYIQI NOX Gas Detector Fixed Nitrogen Oxide Gas Leak Alarm Monitor Meter Tester with Aluminum Shell Material Measuring Range from 0 to 20ppm Free Contact Output Resolution 0.1ppm for Gas Test of Refinery Chemical Plant Boiler Room

Introduction:

Fixed gas detector adopts advanced catalytic gas sensor or electrochemical sensor, which can translate the gas concentration in the air to the digital signal output. 
The detector working with gas controller can be used to detect gas in refinery, chemical plant, LPG station, boiler room, painting plant and other places with gas exists.

It is used to detect the concentration of flammable gas or other toxic and harmful gases in the air. When the concentration reaches or exceeds the preset alarm value, the controller will sound and light an alarm to promptly remind to take safety measures to prevent explosion and poisoning accidents, so as to protect life and property.

This product has the advantages of stable signal, high precision, rapid response, long life, short polarization time, etc. It adopts industrial-grade sensor, the instrument shell is designed with explosion-proof structure, 4-20mA standard signal or directly into the DOS system, and can be widely used in metallurgy, petroleum, chemical, municipal and other industries, and is in the leading level of similar products in China. The housing adopts die-casting aluminum shell with explosion-proof structure design, the groove design of the upper cover can lock the housing, the front side of the sensor is designed with downward structure to ensure good contact between the sensor and the gas, and the inlet port adopts explosion-proof waterproof connector.
