Buyer’s guide for the best Refrigerant Leak Detectors
The factors put into consideration before getting refrigerant leak detectors are different from the factors put into consideration when getting circular blade saws.
When you are looking for an HVAC gas leakage, you need to find the source fast. Only the most accurate leak detector will be able to meet that demand. While looking for the accuracy for any detector, the best sign is to look at the technique it uses for the detection.
Continuous Operation Time
What we mean continuous operation time is that for how long you can use the detector continuously. The reason why you need to consider this factor is that it shows how much time the detector gives to find the leakage.
Beyond the continuous operation limit, you risk exposing the sensor to contaminants. Once the sensor is contaminated, there is no way but to change it. So, get the detector that is not prone to contamination. Almost all the infrared leak detectors are not prone to contamination.
You want to use a detector that is cordless and gives ample mobility in any working environment. That is, most preferred leak detectors are battery-powered. If you see our list, you will find that some detectors use traditional cell batteries and some modern lithium batteries.
Cell type batteries can be recharged. They need to be replaced. And the lithium-ion batteries are chargeable. Both have their advantages. Cell type batteries can run for a long time, whereas lithium batteries need to be charged every 5-6 hours.
But there is one issue with cell type batteries. When the battery is low, the detector may not function properly. But it is not the same with lithium batteries. But sometimes you may not have to charge port nearby you, then for such cases on the detectors with replaceable batteries is the only option. Unlike refrigerant leak detectors, electric gloves and hydraulic bench press do not use battery.
The sensor is the main factor that differentiates one detector to another. So always see the lifetime of the sensor. Some have one year, five years, or ten years. Though the manufacturer may say, its sensor may last up to 10 years, but if it gets contaminated easily, then there is no point buying the detector.
So, always make sure the detector you buy has a well-protected sensor and has a long life.
As the detectors are always used in harsh environments where there are moisture, oil, or different gases, maintenance becomes a key factor. If the detector is not maintained correctly, it loses its accuracy.
So, get the detector that requires a list amount of maintenance. More importantly, the sensor must be well protected. Thus reducing the effort needed for maintenance. The maintenance methods used in refrigerant leak detectors are different from the maintenance methods put in place for tools like PVC pipe detectors and tube cutters, however it is necessary you implore maintenance strategies for these tools.
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.
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.

the Elitech ILD-200, a rechargeable infrared refrigerant detector that is earning rave reviews right now.
One of the reasons why this detector is the most expensive is simply because it has been made to last. It looks solid, fits the hand well, and has a sensor that has been designed to last for ten years before it needs to be replaced. Any of you that have used cheap detectors in the past will know just how frustrating it is when you need to replace far more often than you would like.
As for the sensitivity levels on the ILD-200, there are three pre-set levels with the max level being that of 4g/year. Using the probe on this detector, you will be able to identify if there are leaks of any halogenated refrigerants usually within a matter of seconds.
What we also like about this leak detector is that it will last around six hours of continuous use and that it comes with a rechargeable battery.
|Rechargeable so no batteries needed.||A little too sensitive in high sensitivity mode.|
|Long length probe.|
|10-year sensor life.|
The SRL8 Heated Diode Refrigerant Leak Detector is designed exclusively to make the HVAC/R Technician’s job easier, faster, safer, and more efficient. We set out to develop the best-heated diode leak detector for HVAC/R. We believe the SRL8 is it. It comes in kit form in a rugged, blow-mold case with all of the extras you don’t get from the other guys. (see What’s Included?).
The Fieldpiece ergonomic standalone design fits naturally in your hand. The ruggedized construction stands up to abuse most other leak detectors can’t handle. The 15-hour battery life lets you work all day and then some before recharging.
The included vehicle and wall chargers help you during overtime. The MUTE and ZEROing functions allow you to work the way you want to work. The magnetic hanger helps keep the detector out of the way when repairing a leak, but visible enough so you won’t leave it on the job.
|The battery lasts for two days.||Sensitivity can be too much as it can sometimes pick up the fluorine from soaps.|
|Extremely sensitive and quick to use.|
TEK-Mate is the ideal refrigerant leak detector for the light-to-medium duty user who demands reliable leak detection at a budget-friendly price.

It detects a wide range of halogenated refrigerant chemicals (HFCs, CFCs, and HCFCs), cleaning agents, and other gases which contain bromine, fluorine, and/or chlorine.
|Strong and flexible probe||Known to be a little too sensitive and trigger false alarms.|
|Great value for money.||Struggles a bit with the detection of 134A.|
This is an inexpensive detector that uses the heated diode method of refrigerant detection. This is the process of collecting air and heating it so that chlorine and fluoride ions are separated.
When using this detector, as soon as any refrigerants have been detected the LED display will flash and let you know how severe the leak is across six different levels. We did notice that this detector is not as sensitive as some of the more expensive models but a positive is that it can detect a wide range of different refrigerants and blends.
That sensitivity can be set between 3g/year and 0.1oz/year while the 14-inch probe is longer than many of its competitors. This allows you to reach more difficult areas that some of its competitors will not be able to get to.
|Good length probe.||Fairly lightweight and delicate.|

|Two types of chargers included in the package.||No TFT screen.|
|Accurately detects the leakage.|
When only the best will do, the Robinair TruTrack is ready to go. The TruTrack is an ultrasonic detector that will detect all refrigerant types. It doesn’t stop there, though; you can also hear vibrations from failing bearings, valves, and seals and almost any engine component.
The main issue with an ultrasonic detector is that you must wear headphones to hear the audible hissing. On top of that, the ambient noise int eh environment needs to be quiet as well. If you are looking for an R-134a leak in a car, for example, a noisy working garage may not be the best option.
Aside from that, everything is made easier with this device. You can dial up the sensitivity and begin detecting leaks from a few feet away. As you get closer, you can dial down the sensitivity level to help you pinpoint the location. Follow that with a quick soap bubble test, and you are ready for repairs.
|Can be used for any air leaks, bearings, seals, or other system components.||The detection range varies from inches to feet.|
|Huge, detailed manual included for use and learning.||Must be a quiet environment to hear leaks, even with headphones.|
