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.

СГГ-20Микро – portable flammable gas alarm

 
 

Designed for:
- protection of personnel against effect of pre-explosive concentrations of multi-component mixtures of flammable gases and vapors with air;
- leakage points detection of liquefied (according to ГОСТ-20448-90) and natural (according to ГОСТ 5524-87) gases, hydrogen and other flammable hydrocarbon gases.

Application:
- at enterprises that maintain gas supply pipeline networks or gas equipment;
- at refinery, oil-and-gas production department, oil warehouses, oil transportation enterprises;
- in production premises (boiler houses, gas-distributing stations, gas-distributing point), wells, basements;
- during operation of gas pipelines of low, medium and high pressure ( if there is a probability of forming of explosive mixture of gases of different categories) of underground gas pipelines and during repair-and-renewal operations.

 


Type of gas alarm - individual.
Sampling - diffusion or forced with the use of an exterior flow rate pump or from rubber bulb.
Principle of operation - thermochemical.

All the versions of СГГ-20Микро comply with the requirements of the rules of the Russian Maritime Register of Shipping (RMRS) and of Russian River Register (RRR). When ordering this device with RMRS and/or RRR certificates, be certain to put the letter «Р» at the end of the device name and indicate the type of the required certificate.
