Description
The gas analyzer Sigma 1M is intended for measurement and control of dovzryvny concentration of explosive gases and vapors in air, with formation of the emergency light, sound and operating signals at excess of concentration of controlled gas of the set level.
-
Sigma 1M it is allowed for use by Rostekhnadzor in explosive zones and rooms of the classes B - I, B - Ia and B - Ig according to explosion protection marking ([Exib] IIB" for the panel and "1ExibdIIBT4 X" for sensors). The gas station, municipal networks, warehouses LVZh, gazo - both oil - extracting and processing enterprises and other objects where continuous control of content of explosive vapors in the atmosphere is necessary is applied at pump stations, oil depots.
