  • ✅ 【High Sensitivity & High Precision & High Stability】R134A R410A R22 refrigerant leak detector uses a high-sensitivity sensor, and a built-in mechanical pump pumps air for sampling, providing a positive airflow for the probe sensor, so it can fast respond and detect tiny refrigerant gas. Freon leak detector is controlled by a microprocessor with advanced digital signal processing capabilities to provide you with high accuracy of detection, bringing you high stability and reliability.
  • ✅ 【Adjustable 6 Levels (32X) Sensitivity】The leak detector hvac provides a 32-fold sensitivity increase from 1 to 6 levels. Sensitivity can be adjusted with the sensitivity button, doubling or halving each press. The higher the sensitivity, the faster the sound frequency. Adjust to the required sensitivity according to the detection environment, the measurement accuracy of the halogen gas leak detector hvac will be higher.
  • ✅ 【Sound and Light Dual Alarm】When the gas is detected, the red indicator of freon leak detector will light up and the refrigerant leak detector hvac will emit a buzzing warning. The higher the concentration of leaking gas, the more red lights will be on, and the sound frequency of the alarm will be faster.
  • ✅ 【Environment Reset Function】After pressing "reset" button, freon leak detector will automatically set to ignore the refrigerant concentration on probe sensor, and will only alarm when the refrigerant concentration is higher than the current environment. This feature helps you efficiently track down higher-concentration leaks. (Note:The device automatically turns on the environment reset function by default when starting up. It is recommended to start up in fresh air without refrigerant leakage).
