TGS 4160

The TGS4160 is a hybrid sensor unit composed of a carbon dioxide sensitive element and a thermistor. A wide range of 350~30,000ppm of carbon dioxide can be detected by TGS4160, making it ideal for usage in a variety of applications. The CO₂ sensitive element consists of a solid electrolyte formed between two electrodes, together with a printed heater (Pt) substrate. By monitoring the change in electromotive force (EMF) generated between the two electrodes, it is possible to measure CO₂ gas concentration.

Adsorbent (zeolite) is filled between the internal cover and the outer cover for the purpose of reducing the influence of interference gases.

TGS4160exhibits a linear relationship between EMF and CO₂ gas concentration on a logarithmic scale. The sensor displays good long term stability and shows excellent durability against the effects of high humidity.
