The Gas Clip Technologies MGC-IR-PUMP Multi Gas Clip Infrared Pump is a portable 4-gas detector with an internal sampling pump for confined-space and remote gas monitoring. It detects hydrogen sulfide, carbon monoxide, oxygen and combustible gases using low-power infrared LEL technology. The instrument provides up to 52 hours of continuous runtime, draws samples from up to 75 feet, works in inert environments without oxygen, and supports a 12-month calibration cycle. A one-button interface, large LCD and fully submersible construction support simple operation in demanding industrial environments.
