FSUE “SPA “Analitpribor” is one of the leaders of gas-analysis instrument engineering in the Russian Federation. Production of gas-analysis equipment is from 1960.
 
 

Designed for:
01. Power supply of gas alarms ДАТ-М, alarms СТМ-30-10 – СТМ-30-16, gas analyzers  ДАХ-М, ДАК, ДАМ, potentiometric analyzers of ion activity АП430-02 (hereafter – detectors);
02. Measurement of output current signals of detectors on each channel;
03. Generation of light and sound alarm when values exceed/drop below the set threshold values along with simultaneous switching of “dry” relay contacts.

Application: 
Detection of pre-explosive concentrations of flammable gases and vapors, monitoring of hazardous substances and oxygen content in the air of indoor working area and outdoor facilities of explosion- and fire-hazardous plants and facilities of chemical, petrochemical and petroleum refinery industries.

Units are fixed automatic devices.
