Ammonia NH3 Hanheld Air Gas Sensor

Description

                                     Ammonia NH3 Hanheld Air Gas Sensor

GC***-NH3 detector is a portable phosphine gas detector with intrinsic safety (detector hereinafter), continuously monitors phosphine density. It is applied for phosphine gas leak detection, effectively guarantee the healthy and safety of staff from abuse  gas in the rescue, and also applied in the surroundings such as underground pipe and mine, to keep the workers safe from invasion of the toxic gas phosphine avoiddamage to equipment.

The detector inspects toxic gas phosphine gas leak density by natural diffusion and adopts original imported electrochemical sensor, having good sensibility and excellent repeatability. The device has embedded micro control technique and simple signal display and English instruction menu, making the operation easy. Complete function and dependability makes the whole device a leader in the industry. The cover of the detector is refined from high-intensive engineering material (compound elastic rubber), which made the detector touches well, waterproof and explosion-protection.

>>>>Specification:

The detector especially for phosphine gas density and is widely used in metallurgy, electric factory, chemical, mines, tunnels, thermal power plant , underground pipes etc, effectively prevent toxic accident.
