Description
Type of gas alarm - fixed
Sampling – by diffusion
Principle of operation - electrochemical (carbon monoxide measuring channel)/ thermochemical (flammable gases measuring channel)
Designed for simultaneous monitoring of MPC of working area for carbon monoxide (СО) and pre-explosive concentrations of natural gas (methane) or liquefied gas (propane-butane mixture) in air.
Application
- installation in boiler houses of varying capacity operated on liquefied and natural gases
- installation in non-hazardous areas of other industrial, administrative and residential premises
Distinctive features
- quantity of device versions is reduced with retention of functional capabilities, two versions of СТГ-1-1 (one flammable gas sensor), СТГ-1-2 (two flammable gas sensors) are manufactured
- availability of external input “emergency” that allows to connect devices in loop or to connect them to fire or burglar alarm
- possibility of independent setting of operation modes after device switching on – automatic passing into operating mode opening of network valve - "О" or switching of emergency alarm opening of network valve after pressing of the button "reset" - "В"
- availability of “test” button that allows to check functionality of device and shutoff valves without the use of gas mixtures
- connection by means of terminal connections
- zero autocalibration when activated or once in 14 days

ПГС - поверочные газовые смеси
Поверочные газовые смеси (ПГС) – государственные стандартные образцы (ГСО), эталоны, предназначенные для проведения корректировки показаний и поверки газоанализаторов.
ИР - индикаторы расхода
Предназначены для визуального наблюдения за расходом газовой смеси (ПГС-ГСО) определнной величины, обозначенной риской.
Вентили ВТР, ВЗ, ВР
Предназначены для регулировки расхода газовой смеси, подаваемой из баллона ПГС-ГСО на газоанализатор (штуцер под ПВХ).
ИРР - индикаторы-регуляторы расхода
Предназначены для визуального наблюдения за наличием расхода газовой смеси (ПГС-ГСО) определенной величины, обозначенной риской, а также изменение расхода пробы с помощью регулятора.
