Its adjustable sensitivity ensures automatic and optimal detection status， locating leaks much more accurately. It detects all halogen refrigerants including R134a, R410a, R12, R22, R600a, R404a, R1234yf. Concentration Indicator Once leaking gas is detected, the beep frequency will increase. The more gas leaked, the quickly the buzzer beeps. The first indicator will flash quickly meantime and the other four LEDs will light up accordingly based on the concentration of leaked gases. The first indicator indicates both leak and battery level. Blinks in orange mean low battery. Corona Sensor It will respond to all halogenated. This includes, but is not limited to CFCs e.g.R12, R11, R500, R503 etc. HCFCs e.g. R22, R123, R124,R502 etc. HFCs e.g. R134a, R404a, R410a, R1234yf etc. Blends such as AZ-50. HP62. MP39 etc. 7 Adjustable Sensitivity 1-7 Grade selectable sensitivity Maximum sensitivity is 0.21oz/yr smaller leak, higher sensitivity grade More refrigerants, more rapidly beeps, faster indicator flashes Note: 2 beeps per second when the detector is open, 10 beeps per second when leak is detected) Audible and Visual Alerts LED light flash alarm Buzzer alarm Dual-battery indicators Green - Suitable for job.

A: Yes, it beeps upon powering on, and when a leak is detected, the alarm sound becomes more urgent. Q: Why does the product alarm when not in a leaking environment? A: 1. Probe blockage, clean according to the manual. 2. Probe damaged, replace it. 3. Circuit board damage. Additionally, Temperature greatly affects sensor. Q: Why does the product fail to power on? A: 1.This product does not include batteries, install them before use. 2.Poor contact in the battery compartment. 3.Knob switch damaged. Review: Simple to use, inexpensive, and works. - I ordered this product at the beginning of an auto AC DIY project that went on for months, and didn't get around to actually using it for awhile, but by the time I did, I found that it worked great, and was well worth the price I paid for it. Specifically, it helped me confirm that the valves on both high and low AC service ports were leaking, and that I needed to replace the cores in both valves. It subsequently helped me to confirm that my core replacements worked, and sealed the leaks I was previously detecting. Both the detection and sensitivity functions worked fine for me, and they should for you too, as long as you follow the instructions and don't expect this simple gizmo to perform like some kind of lab grade precision tool. When searching for leaks in unknown locations, the instructions suggest starting with the highest sensitivity level, then gradually decreasing it until you've pinpointed the exact location of the leak. I did the opposite, because I was testing for leakage from two known locations (AC service port valves) ... in other words, I started with the lowest sensitivity, put the tip as close to the valve opening as I could without touching it, and then worked my way up to gauge the severity of the leak. I got a few false alarms in ambient air at the highest sensitivity setting (knob turned until stopped), but wasn't upset about that. Just turned off to clear/reset the internal electronics, started the sequence again at a slightly lower sensitivity setting, and it worked fine. No false alarms when I backed the knob off a little from max rotation, which I see as "normal" for a simple device like this. For example, the control knob just isn't that sophisticated ... it's the same as a combination power/volume control dial on a radio, which probably gets pretty sketchy when it's controlling the "sensitivity" of something as delicate as an electronic gas detecting sensor. This is a BASIC refrigerant leak detector that worked as advertised for me, for a very reasonable cost. Very satisfied. Review: What a cool little tool. Cheap and accurate when used correctly! - I've been struggling to find a tiny leak in my HVAC system. Dye (Twice) with leak sealer failed to seal the leak and it was nowhere to be found for over a month. I decided to take a chance and get this "sniffer" to help locate the leak. Reading the reviews i was a little worried since many people stated it does not work. but after careful research and understanding that the sniffing tip of the unit is ultra-sensitive, I ended up purchasing it anyways thinking i will be very gentle with it. The tool showed up the next day, I put batteries in the unit and activate it and it seemed to perform the initial startup properly. I went to the outside unit (which I already had completely open) and started moving the probe 1/2"-1" from any object but following the copper lines, i went near every soldering point and nothing... I thought for sure the unit is not working. I went back inside and took apart the air handler cover and started following the copper lines and in 5 seconds, the tested start beeping fast as I came close to one of the valves inside the air handler. I then turned the unit off and waited a few seconds to have the air remove any leftover halogen from the tip and started it up again and went in the direction of the same area and again it started beeping. I confirmed that the leak was there by spraying some water with dish soap in it to make bubbles and BINGO! I tightened up that nut and verified with bubbles AND the sniffer that the leak was gone. All in all, the unit performed perfectly when you use it gently and I performed the test multiple times after allowing it to sit unused for a few minutes between tests. ## Features - [All Halogenated Gas] Freon leak detector triggers on R22, R134A, R404A, R410A, R1234YF and all halogenated refrigerants including HFCs, CFCs,HCFCs and blends. - [7 Adjustable Sensitivity] Turn the knob to open and choose the sensitivity level.

Or does it alert you for a leak if it feels air blowing on the sensor? Thank you** A: I am currently a student at a local college working on my last semester of refrigeration and air conditioning technology, I have used this sensor to detect R-22 and R-134a leaks and verified it with a much more expensive sensor. It works for these two refrigerants and yes, it detects the gas not just air. I also use soap bubbles once I have verified the location of the leaks. Best $20.00 I ever spent. **Q: Will this unit detect R421a?** A: The product packaging specifically indicates it will detect R134a, R410a, R12, R22 and R600a (and I've only used mine for R134a), but I'm guessing it'll work with pretty much any commonly used CFC-based refrigerant. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple to use, inexpensive, and works. *by M***K on October 13, 2019* I ordered this product at the beginning of an auto AC DIY project that went on for months, and didn't get around to actually using it for awhile, but by the time I did, I found that it worked great, and was well worth the price I paid for it.

My bad. Amazingly the unit still blinks the LED mostly green even with one of the batteries backwards, just doesn't detect refrigerant. With the batteries properly installed I can spray a small burst of HFC 152a into a cabinet and then the probe detects the refrigerant whenever it's brought near the cabinet. Though after about a minute the refrigerant has dissipated enough that it can no longer be detected (in a mostly closed cabinet) so the sensitivity may not be as high as advertised. original 1 star review *The unit doesn't wnework. The unit powers up properly with the green LED blinking. But there is no change when exposed to refrigerant, even spraying HFC 152a directly at the probe. Tested it outside with no refrigerant and also in the garage, spraying HFC 152a, at different sensitivity levels. Same blinking and beeping in all cases. Possibly it's just a bad unit. I may try another one and if that works I'll update this review. ## Frequently Bought Together - Elitech Freon Leak Detector Halogen Refrigerant Gas Leak Detector HVAC Tester AC Sniffer R22 R410A R134A 1234YF, WJL-6000S - InterDynamics Certified A/C Pro Car Air Conditioner Leak Detector Dye, Detection UV Dye Detects Leaks in R-12 and R-134A Condition Systems, 1 Oz - REALHUNLEE Air Conditioner UV Dye Leak Detector, Pro Auto Oil AC UV Dye Leak Test Detection Tool Kit 68 LED A/C UV Flashlight Detector with Protective Glasses --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/25200165-wjl-6000](https://www.desertcart.nz/products/25200165-wjl-6000) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-06-05*
