Product Specification

Features:

* High sensitivity to refrigerant gases
* Improved selectivity
* Long term stability
* Uses simple electrical circuit

Applications:
* Stationary 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.
TGS 832-F01 has high sensitivity to commonly used refrigerant gases in air
conditioning systems and refrigerators such as R-134a, R-404a, R-407c, and
R-410. TGS832-F01 uses filter material in its housing to eliminate the influence of
interference gases such as alcohol, resulting in highly selective response to CFC’s.
This feature makes the sensor ideal for stationary type leakage detectors which
require durability and resistance against interference gas.
