If there’s a leak present, the refrigerant will pass through the electrodes and, in turn, interfere with it (it causes a drop in the current). The drop in current will sound an alarm. The more the interference, the higher the concentration and the larger the refrigerant leak." It's a tried and true method. I was able to easily find my leaks with this product. You must let the product "heat up" for about 10 seconds before you use it. Just turn it on, and hang out for 10 seconds. Finally, the unit beeps all the time...maybe about once a second...while it's in detection mode. That might irritate you. It doesn't bother me. If it finds a leak, the beeping speeds up significantly which is easy for my ears to hear. If you don't want to hear it beep all the time which it's detecting, get the newer model that they sell. Costs a little more. Overall, I am very happy with this product. Good bye soap! Review: Works great, but you need to know where to look for the leak. - I have used this to successfully find refrigerant leaks on 2 different cars. Since the leaks are extremely slow, you have to get the probe very close to the leak. The second leak was found initially using leak detection fluid, I.e., soapy water. I saw a slight bubbling, then put the probe close to it, and the alarm went off. There was a tiny crack in the swaged collar on the compressor discharge hose. I recommend using both the “sniffer” and the leak detection fluid in combination. ## Features - 【Certificated by SAE-J1627 and EN14624 Standards】Stop false alarms from soap bubbles solution. CLD-100 【With UV + White flashlight】, an advanced version of WJL-6000. Continuous detection mode, instantly responding to all halogenated gases (including chlorine, fluorine, bromine): [CFCs: R12, R11, R500, R503 etc.] [HCFCs: R22, R123, R124, R502 etc.] [HFCs: R134a, R1234yf, R404a, R125, R438a etc.] [HFOs: R1234 etc.] [Hydrocarbon: R290, R600a etc.] [ Blends: AZ-50, HP62, MP39, R410a etc.] - 【6 Modes of Sensitivity to Reach the Best Detection】20cm flexible sensing tip with max.sensitivity of 0.21oz/yr(6gr/yr). You can manipulate the probe into the way you want to go. It's powered by 4 AAA batteries with low Battery Warning. - 【The Less Warm-up Time】Warm-up time < 6s. Reset time: 2~10s. Reset function sets itself to ignore the ambient level of Halogen gas. - 【Automatic Zero-Point Calibration with Visual and Audible Alerts】It starts to BEEP and FLASH REGULARLY after being turned on in the flesh air, any leak above zero will be detected.

CLD-100 can't detect R600a and flammable refrigerant. Because it's corona technology. If you have any question, pls feel free to contact us. We're a HVAC direct factory with 27-year experience. Xetron Support Team **Q: Will it detect 407c the replacement for R22?** A: Yes, it can detect R-407C refrigerant, as well as R22 **Q: Please expand on what 24 hours of sensor life means. Is it 24 hours of use or 24 hours from the time it is unpacked?** A: Hello, it means 24 hours of use. After this time, the sensitivity of the leak detector will also decrease over time. **Q: Hi. are the sensor tips of cld-100 changeable/ repairable? do you sell sensor tips for cld-100? if yes, may you provide me with the link?** A: Hello, the sensor tips of CLD-100 can be replaced, but we do not sell this accessory, because the price is not cheap, and generally most people do not have the ability to replace the accessory by themselves, so we recommend just replacing it with a new one. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works very well, found my leaks *by A***R on June 22, 2024* I was specifically looking for a product that did the following: - used electronic method for finding leaks; I despise using soap or ultraviolet - used one of the following electronic methods: Corona; heated diode; ultrasonic - uses normal batteries (this one uses 4 AAA); some models use C batteries which I don't have a recharging system for This one uses the Corona method which means: "The instrument uses two electrodes with a current of a known baseline passing between the two electrodes.

Found the leak using the tool - fittings not secured properly. I know professionals use much more sensitive and expensive units, but for the cost this seems good value and based on gas prices saved me either a callout charge and further wasted gas Have also used this on my car ac system which I recently refitted - confirm no leaks in the system ## Frequently Bought Together - Xetron HVAC Refrigerant Leak Detector with UV LED,Automotive AC [R134A R410A R22 R1234YF] Freon Sniff Halogen Gas Leak Detector, 6 Adjustable Sensitivity, CFCs HCFCs HFCs HFOs CLD-100UV - 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 Auto Air Conditioner Leak Detector Tool Flashlight Oil AC UV Dye Leak Test Detection Kit Pro 68 LED Flashlight with UV 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.us/products/505221057-hvac-refrigerant-leak-detector-with-uv-led-automotive-ac-r134a](https://www.desertcart.us/products/505221057-hvac-refrigerant-leak-detector-with-uv-led-automotive-ac-r134a) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-13*
