Hazards & Toxic Symptoms
Freon generally refers to halogenated hydrocarbon refrigerants such as R12/R22/R134a/R404a. It is inherently low in toxicity, but leakage in enclosed spaces can displace oxygen and lead to asphyxiation. CFCs/HCFCs are ozone-depleting substances (CFCs have been banned under the Montreal Protocol).
Typical Application Scenarios
- Cold storage / central air conditioning room
- Refrigerated and frozen transportation
- Industrial refrigeration equipment
- Aerosol propellant
Detection Principle / Recommended Sensors
Infrared (NDIR) / Semiconductor Halogen Sensor
Common Range：0-1000 ppm
