TGS832-A00 Gas Sensor, Brand Name : Figaro for leak detectors

Tgs832-a00 - for the detection of chlorofluorocarbons
features:
* high sensitivity to refrigerant gases
* quick response
* 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 (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 tgs832-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.
