New range of low cost carbon dioxide sensors

Designated the GasCheck family of products they feature high accuracy, long term stability, negligible cross sensitivity, small size and low power requirements

Edinburgh Instruments is now manufacturing an expanded range of low cost high performance infrared carbon dioxide sensors.

The GasCheck sensor products are available in three ranges: 0-3000ppm, 0-3% and 0-10% by volume with a 0-1V non-linear output.

A linearisation board can be added as an option to give linear 4-20mA output.

Some models are available with the option of a 'self referencing' facility, which alerts users to check calibration parameters.

This option offers self referencing against source variation warning when calibration may be necessary.

Gascheck sensors are available with a diffusion-aspirated sensor head as an alternative to the standard pumped-aspiration format.

Operating temperature is 0-45C with a power consumption of 0.9W and output signal of 0-1V (non linear), 4-20mA (linear version).

These innovative products have many uses, with applications including measurement of CO2 in biological incubators, personal safety, gas combustion and delivery, process control, horticulture, plant physiology, heating and ventilating, medical/veterinary applications.
