FIGARO
PRODUCT INFORMATION
TGS 831 - for the detection of Chlorofluorocarbons (CFC's)
Features:
* High sensitivity to R-21 and R-22 * Low dependency on temperature and
humidity * Quick response * Uses simple electrical circuit * Ceramic base resistant to severe
environment
Applications:
* Refrigerant leak detector
The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductor which has low conductivity in clean air. In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.
The TGS 831 has high sensitivity to R-21 and R-22.
