The Portable Pumping Multi-Gas Detector is a high-performance safety instrument designed for professionals working in hazardous or underground environments. This versatile device provides simultaneous monitoring of five critical gases—Carbon Monoxide (CO), Hydrogen Sulfide (H2S), Combustible Gases (LEL), Oxygen O2, and Carbon Dioxide CO2—utilizing a sophisticated blend of electrochemical, catalytic, and infrared sensor technologies. Equipped with an integrated internal pump and a vital mandown alarm function, it ensures that if an operator becomes incapacitated, an immediate alert is triggered through sound, light, and vibration, providing an essential lifeline in high-risk scenarios.
Engineered for durability and ease of use, the unit features an IP67-rated housing and carries ATEX/IECEX certifications, making it suitable for the most demanding industrial settings. The clear, multi-numerical display provides real-time data along with TWA, STEL, and peak values, while the large-capacity rechargeable lithium-ion battery ensures long-lasting performance during extended shifts. With added security features like password protection and a one-click data logging export, this detector is an all-in-one solution for comprehensive atmospheric monitoring and worker protection.
