* Long term stability
* Uses simple electrical circuit

Applications:

* Portable and fixed installation refrigerant leak detectors

The sensing element of Figaro gas sensors is a tin dioxide (SnO 2 ) 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 832-A00 has high sensitivity to refrigerant gases commonly used in air
conditioning systems and refrigerators such as R-134a, R-404a, R-407c, and R-410.
TGS832-A00 has a gas diffusion hole in the sensor cap as well as in the sensor
base. By using the sensor with a suction pump, response speed can be accelerated,
making it suitable for portable gas leakage checkers.
