A freon leak detector is a device used to detect and locate leaks in cooling systems that use freon or other refrigerants. Freon, also known as chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC), is commonly used as a coolant in refrigeration and air conditioning systems. The leak detector works by sensing the presence of freon gas in the air. It typically uses a heated diode sensor or an infrared sensor to detect the gas. When a leak is present, the freon gas escapes and is detected by the sensor. Freon leak detectors play a crucial role in maintaining the safety and efficiency of various systems that utilize refrigerants.
Freon leak detectors are essential tools in the HVAC (Heating, Ventilation, and Air Conditioning) industry for detecting and locating refrigerant leaks. Timely identification and resolution of freon leaks help prevent environmental damage, improve system performance, and ensure compliance with safety regulations. These devices are designed to detect and locate leaks of Freon, a type of refrigerant commonly used in cooling and air conditioning systems.

The Freon leak detectors installed at the site or back of the environmental chambers are powered by the controller. When a gas leak occurs, the sensor converts the leak amount into a corresponding voltage signal output, and the voltage signal is uploaded to the controller after being processed by the detector, and the controller parses the data and displays it on the screen after receiving it. When the concentration reaches the set action value, the controller will send out an alarm.
