Description
Overview
GAO Tek portable infrared biogas monitor detector which is based on advanced infrared and Electrochemical technology for measuring 100% CH4,100% CO2, 30% O2, and 2000 ppm H2S concentration, with optional H2, CO, gas flow items. SAZA RCD4 Multi Biogas detector adopts a dual infrared sensor (CH4&CO2), and an internal electrochemical sensor (O2, H2S) designed to achieve easy maintenance in daily operation. It’s non-thermostat container design, and special correction method greatly eliminate the temperature impact on infrared sensors
