  • 10 Years Infrared Sensor Lifetime: Elitech independently developed the latest infrared sensor, greatly extending the sensor life up to 10 years; compared to traditional sensors, the results are also more accurate for all halogenated refrigerants.
  • TFT Screen: First leak detector with a TFT screen that gives more clear and easy readings on sensitivities, leakage alerts, battery levels and other key info during operations.
  • Higher Sensitivity: Adjustable sensitivity with High/Medium/Low levels and the maximum sensitivity is up to 0.1oz/yr.
  • Quick Operation: The two corresponding buttons on the front allows quick adjustment to sensitivities or to mute buzzer directly, very easy to operate.

Description

Elitech Vision: AI Tools Create Green Future Elitech has set up 120,000 square meters of modern factories in China, and we also have plans to open factories in Vietnam and North America in the future to increase production capacity. Our mission is to lead the new generation of intelligent HVAC tools by combining intelligence and innovation in the refrigeration industry and making all work easier. We will focus more on the research of digitalization and intelligence of all kinds of instrument tools in low carbon, and create a green future together with our users and partners. More than 200 Engineers: Independent Research & Development The ultra-sensitive sensor of Elitech ILD-300 Leak Detector allows it to detect even the most difficult ones like R-134a, R-404A, R-407C, R-410A and 1234yf refrigerants. Our exclusive solid electrolyte sensor technology reduces heat and gives the sensor longer life than traditional heated diode or corona detectors. Elitech Infrared Refrigerant Leak Detector is designed exclusively to make the HVACR Technician's job easier, faster, safer and more efficient. We set out to develop the best refrigerant ac sniffer for HVACR. The Six-hour battery life lets you work all day before recharging. The sound and light alarm allows you to work the way you want to work. This infrared leak tester allows it to detect even the most difficult ones like R-134a, R-404A, R-407C, R-410A and 1234yf refrigerants. Our exclusive solid electrolyte sensor technology reduces heat and gives the sensor longer life than traditional heated diode or corona detectors. Flexible Probe Allows detection in difficult and hard-to-reach areas Replaceable filters to keep clean of the sensor Respond to all halogenated (contains Chlorine of Fluorine) refrigerants. Automatic Self Calibration within 3s What are the features of the infrared IR sensor in ILD-200/300? The infrared IR sensor's sensitivity remains stable for 10 years, unaffected by humidity or oil, and nearly equal for most refrigerants. It detects concentration changes, so the wand must keep moving. What are the features of the heated diode sensor in ILD-100H? The heated diode sensor detects absolute concentration levels, allowing sustained beeping at leaks and high initial sensitivity. However, it loses sensitivity over time, requires replacement, and shows varied sensitivity to refrigerants. How long does the sensor last? If it seems like your leak detector is no longer picking up leaks or is not as sensitive as it was when you first bought it, try replacing the filter. This should fix the issue. If this does not fix the issue try replacing the sensor. Why is it necessary to move during the detection process? As ILD series are designed to detect the relative concentration of gases, that if the detected concentration remains unchanged in the stationary environment, it will not be able to pinpoint the leakages. Why does the product alarm when not in a leaking environment? 1. Deformation of the optical chamber affects detection data, a normal occurrence. 2. Loose critical optical filters, we could provide repair assistance. 3. Check for routers or devices causing electromagnetic interference.

Best leak refrigerant detector

Worked like a champ. Found my leak immediately.
Color: Infrared Sensor Ild-300 Style: Infrared Sensor
Bought this cause it was my last resort on finding a leak ive had for a while. I dont like the dye and glasses and all of that junk because if its leaking bad enough it will get into the fan and spread all over the engine block specially around the compressor. So after reading reviews and talking to some ac folks they recommended this detector. In the video above you will immediately found my leak on the compressor seal and also some small leaks on the fittings. Awesome product for the money. Would recommend has a nice case with it as well to protect. I would recommend to put this product in your home in the closet or somewhere safe to keep out of humidity and moisture don't just store this in the tool box and also remove the batteries as well so it doesn't mess up the connections from leaking acid. Awesome product. 5 stars ... show more

Waste of Money; Use about 200 PSI of Nitrogen & Soapy Water & Save Money
Color: Infrared Sensor Ild-300 Style: Infrared Sensor
Purchased this detector about 5 years ago. I tried finding automotive a/c (R-134a) leaks several times during the 1st year but I always had to resort to charging the A/C with 200psi of nitrogen, then with the use of soapy water I would easily find the leak, so this has just been collecting dust inside of my home. I decide to try it rather than evacuate the refrigerant and charge with nitrogen a few days ago but it wouldn't accept a battery charge. It never found even 1 large leak before dying. For me, it was just a total waste of money. Nitrogen and soapy water finds the leak regardless of the type of refrigerant, this junk never once found a leak for me before completely dying after the warranty expired. ... show more

Good luck if you have a warranty problem
Color: Infrared Sensor Ild-300 Style: Infrared Sensor
It will detect most freon leaks and seems to be pretty good. I bought 4 of them for my business and one quit working. I was instructed to ship back to a foreign country which costs about $150. Still waiting buy at a risk the warranty is a bad joke.

The best detector I have ever used!

Great R410a detector! No false readings. It pinpointed my R410a leak down to the loose cap on a TXV valve. Even my A/C Tech was impressed with it.
