About this item

  • 【High-Precision Sensing】The refrigerant leak detector uses an advanced heated diode sensor, which is 20 times more sensitive than ordinary soap bubbles. Gas leak detector can accurately detect refrigerant leaks in various environments and quickly help you determine the occurrence of problems.Maximum sensitivity:0.05oz/yr (1.5g/a)stationary; 0.1oz/yr(3g/a) in motion。With a probe length of 51cm,freon leak detector allows you to easily cope with more complex scenarios and reliably help you solve problems.
  • 【Digital Display, LED Indicator】Freon leak detector instrument is equipped with a digital display (0 to 9). The higher the reading, the greater the leak at the monitoring point, allowing you to clearly observe the dangerous degree of the leak. The 3 LED lights from left to right represent the sensitivity level of high, medium and low. When the indicator shows 0 and the blue sensitivity LED lights up, the refrigerant leak detector is ready and you can start leak detection.
  • 【Silent Setting, Buzzer Alarm, Failure Warning】 When you need to work in a quiet environment, long press the mute button to turn on the silent mode. Note: After muting, the mode will remain in this state and needs to be changed manually. When a leak occurs, the ac leak detector will emit a buzzer alarm, allowing you to easily find the location of the leak. When the sensor output is abnormal, a horizontal bar appears in the middle of the digital display and a short alarm sound is emitted.
  • 【Wide Application】Freon leak detector hvac instrument can identify a variety of halogen refrigerants, including HFC /HCFC /CFC /HFO R134a R22 R1234 and other categories. You can use the instrument to check whether there is leakage in hidden places such as pipes, hoses, and welding gaps. In addition, you can also perform detection in different working environments to ensure your travel safety.
  • 【Humanized Design】Refrigerant leak detector hvac leak detector is equipped with four AA alkaline batteries and can be used continuously for 4 to 6 hours, which provides you with a guarantee for long-term use. The probe can be bent at multiple angles, so in complex environments or dangerous places, the refrigerant leak detector can help you easily deal with it. And a reasonable hand-grip design is adopted to prevent the device from slipping.
  • 【Replaceable Sensor, Manual Zeroing】 When the sensor fails or you find that the sensor cannot detect normally, you can manually replace the sensor. After the replacement, you can continue to use it normally. The freon leak detector works in the automatic zeroing algorithm mode, but in some cases, manual zeroing is required. You can press the environmental zeroing button and the leak detector will be forced to zero.
  • 【Three-year Warranty Service】 Our products come with a three-year warranty period. If you encounter any problems during use, you can contact us. We will do our best to help you solve them and provide you with the best service.

  • Visually trace the entire refrigerant system, and look for signs of air conditioning lubricant leakage, damage and corrosion on all lines,hoses and components.
  • Always follow the refrigerant system around in a continuous path so that no areas of potential leaks are missed. If a leak is found, always continue to test the remainder of the system.

NOTE

  • Always leak test with the engine off!!!
  • Always use a grounded outlet
  • Always wear Proper Protective Equipment(PPE), which includes gloves and safety glasses
  • Handle hoses and equipment carefully as refrigerant is under high pressure and can cause frost bite
  • Perform leak detection in accordance with recommended practice to verify working environment is free from leaking refrigerant as it can be toxic and or flammable
  • Only work in well-ventilated areas (minimum of 4 air exchanges per hour)

Unfortunately (or fortunately) I do not have any refrigerant leaks at the moment I can test for. I did test it on a vehicle, refrigerator and my HVAC unit, but nothing registered, as expected. I have been in a situation where I had a small leak in a vehicle before and trying to locate a very small leak is very difficult. I added this to my AC tools, so in the future I have the tool on hand when it is needed. It is easy to use, and just a good tool to have on hand when you need it.

I was very impressed with how accurate and sensitive this could be. I was able to pinpoint a leak on a system where there was no dye. Ready to use in a few seconds, easy to adjust sensitivity, and easy to use! I was extremely happy with the results I got from this. No need for an expensive name brand!

It detected a very small leak that I didn't know was there on a car with working AC that's 16 years old. So I'd say it is very sensitive. It's pretty easy to use with instructions and warms up in 35 seconds.

Leak detector works very well. Used to identify leaks on HVAC systems using R-22, R-410A and R-32. Performed really well on each refrigerant type. Very pleased with the product. Glad to use 4 AA batteries instead of having to re-charge between leak checks. Good value for the cost.
