CO₂ Sensors

The GasCheck is a series of low cost CO₂sensors 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.

Key Features

Analogue electronics.
Long-term stability.
Robust construction.
Gold-plated optical reflector.
