The 5 Best Refrigerant Leak Detectors Reviews & Buying Guide

There are a lot of things like ACs and refrigerators that rely on a refrigerant for cooling and their proper functioning. Due to this, it is highly essential to make sure that this refrigerant does not leak and come out. To detect any such issues, there are a lot of refrigerant leak detectors out there that can be selected based on these factors:

  • Sensitivity: The sensitivity of your refrigerant leak detector is important to know as high sensitivity leak detectors are required to check for small leaks. While some models are rated at 0.25 oz/year and others at 0.15 oz/year where lower is better.
  • Sensor Life: All of these refrigerant leak detectors use a sensor that has a limited life before they stop working. Generally, this sensor life is given as 100 hours or 200 hours with some models, including a sensor life rating in years.
  • Battery: Most of the leak detectors available out there are battery powered for ease of use. Because of this, checking the supported battery type as well as battery life are quite important to check since you have to change or charge the battery once it runs out.

You can only fix a refrigerant leak after you have detected it, which makes refrigerant leak detectors highly essential and useful. Thus, today, we are here with some of the best refrigerant leak detectors.

We have also provided all their important details along with a detailed “Buying Guide” in this article. These things can be handy to differentiate between these refrigerant leak detectors and buy the right one for you after following this article until the end.

Buying Guide for the Best Refrigerant Leak Detector

Just per the name, a refrigerant leak detector gets used for detecting and informing you about any refrigerant leaks. These leaks might occur in your fridge or even in an AC unit in certain circumstances. And thus, we have mentioned the best refrigerant leak detectors in this article. To help you in choosing the right one, we have also mentioned their major features and options.

That being said, if you are still confused about these leak detectors, then this detailed buying guide is just for you. This buying guide for the best refrigerant leak detector will take you through all of the factors that you would want to know before getting one. In other words, make sure to follow this buying guide until the end:

1. Detector Sensitivity

If you want a given refrigerant leak detector to work properly, then it needs to be sensitive enough to detect small leaks. There are a lot of cases when the refrigerant might leak in a very small amount. But even this small amount can affect the cooling performance by a lot over time.

Thus, a given leak detector should be highly sensitive and able to detect small leaks as well. As a result, these refrigerant leak detectors come with a sensitivity rating like 0.25 oz/year or 0.15 oz/year. Out of these two options, the later lower rating is better since it offers higher sensitivity as it can detect much smaller refrigerant leaks.

Generally, these refrigerant leak detectors come with controls that allow you to adjust this sensitivity as per your needs.

2. Sensor Life

Just per the name, a refrigerant leak detector uses a sensor for detecting any refrigerant leaks. Unfortunately, this sensor has a maximum work-life and needs to be replaced afterwards. If you want to use your refrigerant leak detector for a long time, then it needs to have a long sensor life.

In some cases, this sensor life is given in days as 100 days or 200 days. You can also find a few refrigerant leak detectors that offer a much longer sensor life in years. Such leak detectors are made for heavy-duty usage and ideal for long term usage.

3. Battery and Battery Life

A great thing about most refrigerant leak detectors is that they are completely wireless. As a result, you can check for refrigerant leaks without the need to have a power source. They are able to do this since most of them are powered by a battery that powers the sensor as well as the rest of the functional components.

Although, as you would expect, this battery will run out sooner or later. In some cases, this is a replaceable battery and a rechargeable one in others. For both of these cases, checking the battery life that suits your work needs is highly essential. Other than that, checking the battery type is also important so that you can get the correct replacement batteries for your refrigerant leak detector.

4. Supported Refrigerants

If you are familiar with refrigerants and cooling equipment like refrigerators and AC, then you must know that there are a lot of different gases that get used as a refrigerant. Because of this, some specific refrigerant leaks might not be detected by a given detector.

To overcome this issue, you should get a refrigerant leak detector that supports a wide range of refrigerants and detects them properly in case of a leak. Thankfully, almost all refrigerant leak detectors come with a list of various supported refrigerants that you should check. It includes various CFCs, HFCs, HCFCs, and other refrigerant types, as well as their mixes.

5. Warranty

Apart from having a long-lasting sensor, the whole leak detector unit also needs to be reliable and durable if you want to keep using it for a long time. And the easiest way to ensure this is to check the warranty offered by your refrigerant leak detector.

Different models come with different warranty periods, which include options like a 1-year long warranty or a 2-year long warranty. When compared, any leak detector that offers a longer battery life is considered to be more reliable and durable.

A few refrigerant leak detectors also come included with a carrying case that can be handy for easily storing as well as taking the detector with you to a remote job site without damaging it.

Conclusion

There might be a few rare cases where the refrigerant of your AC or refrigerator might leak out, which can affect the cooling performance by a lot. To prevent such issues, checking on such leaks is highly important using a leak detector.

Hence, we have presented the best refrigerant leak detectors along with all their details in this article.
