Overview

Enviro Forest’s portable oxygen gas detector with pump suction and multi-unit display is designed for precise O2 measurement using catalytic combustion, electrochemistry, and infrared absorption principles. This device offers pump suction or dispersive sampling and supports customizable measurement ranges. It features a durable full metal jacket housing, a user-friendly interface with navigation keys, and supports both Chinese and English languages. The detector stores up to 100,000 data groups and uses an intelligent algorithm with multi-point calibration and temperature compensation for accurate results. Powered by a high-capacity lithium-ion battery, it delivers over 20 hours of continuous operation. It also includes an acousto-optic alarm to alert users when gas concentrations exceed safe levels, with IP66 protection for harsh environments.
