Chlorofluorocarbons (CFC's) sensor TGS830

Description:
The TGS 830 has high sensitivity to R-22 as well as to R-11, R-12, and R-113. Due to its low sensitivity to hydrogen and alcohol vapors, the sensor can achieve good selectivity. Combined with its long life, this makes TGS 830 an excellent, low-cost sensor for CFC detection.

Specifications:
1) range：100-3000 ppm
2) sensitivity (change ratio of Rs) : 0.30±0.10
3) Circuit Voltage：Max. 24V (DC only
4) Heater Voltage：5.0±0.2V DC/AC

Features:
1) High sensitivity to R-113, R-22, R-11, and R-12
2) Low sensitivity to hydrogen and alcohol vapors
3) Uses simple electrical circuit
4) Ceramic base resistant to severe environment

Application:
Refrigerant leak detectors
