Product Details

1、 Product Overview

The GDB1 wall mounted gas detection alarm can be applied to detect hazardous gas leaks. It uses electrochemical/catalytic combustion sensors and has the advantages of stable signals, high accuracy, and integrated instrument sound and light alarm display. The explosion-proof wiring method is suitable for various hazardous areas and is widely used in ammonia refrigeration workshops, steelmaking and iron smelting workshops, gas cabinets, coke oven rooms, pharmaceutical purification workshops, tobacco fumigation workshops, chemical plant synthesis workshops and other places that require poisoning and suffocation prevention.

The housing of the GDB1 wall mounted gas detector adopts anti slip, waterproof and dustproof design, which is suitable for use in various complex occasions. Instrument intrinsic safety explosion-proof design, explosion-proof mark: Ex dIICT6.
