OLC(T)10 EXPLO Gas Detectors for Explosive Gases

OLC(T)10 EXPLO Gas Detectors for Explosive Gases

Quick Overview

The OLC(T)10 Flammable gas detectors are designed for commercial applications and units are available for safe area and hazardous area applications. These detectors are ideal for the continuous monitoring of flammable gases present in car parks or boiler rooms. the OLC10 TWIN units can be connected in a single line to allow two detectors to connect back to the one controller channel. These detectors provide a wheatstone bridge or 4-20mA output.
Hazardous Area Approved
