The Gas Clip MGC Pump is ideal for confined space entry. This multi-gas IR monitor tests for the OSHA-required H2S, CO, LEL, and O2 concentrations and features an internal sampling pump which can pull air to the sensors from up to 75 feet away. The IR LEL (combustible gas) sensor uses very little energy and allows the unit to work a full week of detection on a single charge. The MGC-IR-PUMP uses low-power photometric (IR) technology to detect combustible gases (LEL). The power-sipping IR sensor allows the monitor to have incredibly long battery life. Another advantage of the Gas Clip IR sensor is that it’s immune to silicon or H2S poisoning from over-saturation.
