The detector flammable gas WATCH-

The detector flammable gas WATCH-

The purpose

Stationary gas detectors - gas detectors harmful substances designed for continuous automatic measurement of content one or more components of the gas mixture and issuing alarm when exceeding the maximum permissible concentrations in accordance with GOST 12.1.005-88.

Gases

sulfur dioxide

nitrogen dioxide

oxygen

carbon monoxide

hydrogen sulfide

ammonia

chlorine

Application

The oil, gas, chemical, food and other industries.

Dignity

Microprocessor system information processing and self-diagnostics

Built-in light and sound alarm for each channel

Automatic adjustment of the "zero"

Digital readout device gas concentration

The ability to control external devices

automatic malfunction-free transition to backup power in case of principal

the presence of the current and digital outputs

the ability to simultaneously control MPC harmful gases and dovzryvoopasnyh concentrations of combustible gases.
