Gascheck - Infared Gas Sensors for Low Cost CO2 Detection
From OEM Gas Sensors
The GasCheck is a series of low cost CO2 sensors that offer high accuracy, good long term stability, negligible cross sensitivity, small size and low power requirement. The basic GasCheck is available in three ranges 3000ppm, 3% and 10% with a 0 to 1 V non-linear output. A linearization board can be added as an option to give linear 4 to 20 mA output. The option of a diffusion assembly is available for the 3000ppm unit. All orders are shipped with free logging software information on a USB key. You will simply need to purchase a cable.

Product Overview
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 compact design.
