Product Code: 2S51А4M
Gas detector “Srazh” 2S51A4M is intended for automatic control of gas concentration (hereinafter methane) and carbon monoxide in the air explosion-proof areas of domestic, municipal, industrial buildings and boiler rooms.
Gas detector passed state tests for compliance with Ukrainian national standardization system EN 50194.
Devices are produced in shockproof plastic casings, it is fixed version with built in light and sound display.
