NA-300 gas alarm detector

Affiliate classification
Product Details


The NA-300 gas detector is a new type of detector developed by our company for long-term continuous monitoring of the content of combustible gas in the air. It can convert flammable gas and toxic and harmful substances into DC4-20mA standard signal output. When it exceeds the calibrated value, it will give an alarm. Especially, it is suitable for flammable and explosive toxic places where the working environment is not difficult and the workers are not easy to get close to.

product details

1. The casing is designed as a double chamber

The electrical cavity is completely isolated from the outside world, and the wiring is realized in the wiring cavity without opening the machine casing.

easy to use

The remote control realizes on-site adjustment and maintenance without opening the cover.

Sensitive sensor

Catalytic combustion sensors are more sensitive.


The scope of products

Widely used in the detection of chemical, mine, steel, petroleum, pipeline, pharmaceutical, decoration, fuel, food processing, laboratory enthalpy, gas leakage and other toxic and harmful, dyeable gases.
