Infared gas sensors: Gascheck Range GASCHECK For Low Cost CO2 Detection KEY FEATURES • Analogue Electronics • Robust Construction • Single Channel • Gold Plated Optical Reflector • Long Term Stability • Solid Aluminium GAS SENSORS The Gascheck Infrared Gas Sensor Range, supplied by Edinburgh Sensors offers high performance, cost effective detection and measurement of CO2 with a choice of pumped or diffusion aspiration technology to provide accurate and reliable determination of CO2 gas concentrations. The Gascheck family includes instruments to measure CO2 in the ranges 0 – 3000ppm, 0-3% and 0-10% by volume. Other features include the option of indicating CO2 concentration using linear (4-20mA) or non-linear (0 – 1V) signal output. Originally developed for measuring CO2 concentrations in laboratory incubators, the Gascheck range has now also been adopted for a wide range of applications where accurate measurement of CO2 is required, but with the benefits of low cost and co
