Versatile Combustible Gas Detection
An explosive environment is created when combustible gases or vapors reach levels that are between the lower explosion limit (LEL) and the upper explosion limit (UEL). Methane, for example, has a LEL of 5% volume and UEL of 15% volume. These levels differ depending on which combustible gas is present.
The G600 series audible and visual alarms will be triggered long before an airgas mixture has reached a dangerous concentration. The alarm threshold is usually set to 10% LEL, if not otherwise specified. The measurement principle for combustible gases and vapors in the percent LEL range is detected with a stable catalytic combustion sensor.
Various models of the G600 series use an additional detection principle on the basis of a thermal conductivity sensor. Using this system, combustible gases can be measured in concentrations up to 100% volume. Other models are available with additional ppm or micro range readings. With its internal sampling pump, extremely small amounts of gas can easily be detected from leaks in pipelines, valves and fittings.
G634P
The G634P model is ideal for measuring, detecting and warning of leak warning for combustible gases and vapors.

…and wherever life and/or property needs to be protected against hazardous combustible gases or vapors.
As the G600 thermal conductivity system shows only a minimal interference by carbon dixide (CO2), this instrument is suitable for direct landfill measurements without filters. The EXOTECTOR’s functional features make it a high performance, reliable gas detector.
