Review: It worked amazingly well and saved me $8000 on a new mini spit installation. - Worked amazingly well after failed attempts with a halogen leak detector and 300 psi nitrogen and soap bubbles. I found the leak in my Gree AC heat pump in minutes after spending $1000 over the years on recharging. The leak was a manufacturing defect with a pinhole under perfect evaporators fins. Pulled away the fins and brazed the pinhole shut, vacuumed and recharged. I understand using the ultrasonic noise generator it is great for finding water leaks in cars an other weatherstripping.
Review: Good deal - Works well on most leaks. Perfect for what we got it for.

## Features

- Operation Modes for Diverse Applications: Professional ultrasonic leak detector, Widely Used in HVAC & Automotive. EM282-R features both Active and Passive modes. In Passive mode, it can be used alone to detect leaks in pressure and vacuum systems. In Active mode, combined with the EM282-T transmitter, it can perform tightness checks on non-pressurized containers and sealed compartments like cars, ships, and refrigerators, offering a wide range of applications. Also it doesn't work for low pressure.
- Precise Leak Location for Efficient Fault Detection: Dual LED & Audio Alarm, Utilizing advanced ultrasonic sensing technology, the detector can identify ultrasonic emissions caused by gas or liquid escaping through tiny openings. When the probe approaches a leak, the "LEAK" LED lights up and the ticking tone in the headphones increases in frequency. The higher the frequency, the closer you are to the leak, allowing for quick and accurate location of the problem.The sensitive sensor picks up the 40kHz ultrasonic sound. The "LEAK" red LED lights up and the ticking alarm in the headphone increases frequency as you get closer to the leak, helping you pinpoint the exact location.
- Portable and User-friendly Design: Automotive ac leak detector is compact and lightweight, the EM282-R is easy to carry and operate. Simply plug in the headphones, press the "TEST" button, and adjust the sensitivity knob according to the environment. No complicated training is required, making it accessible for users to perform detection tasks on-site.
- High Sensitivity for Reliable Detection in Various Environments: The air leak detector can be set to the highest sensitivity level to capture even weak ultrasonic signals from leaks. In noisy conditions, the sensitivity can be adjusted to filter out background noise and ensure accurate detection of leaks, providing reliable results.
- Durable and Low Maintenance: HVAC Leak Detection is built with a sturdy structure, the EM282-R is resistant to damage and can operate in temperatures ranging from 0℃ to 40℃ and humidity levels below 80%. Output Frequency :40kHz. Powered by 2 pcs 9V 6F22 battery, it offers easy replacement and stable performance. With a recommended battery change after 10 hours of continuous use, it ensures low maintenance costs and long-term reliability.

## Questions & Answers

**Q: will it or can it detect smallest movement of water flow in a pipe?**
A: Sorry, we are afraid that the ultrasonic leak detector is unable to detect smallest movement of water flow in a pipe.
this air leak detector is tested by ultrasonic. The ultranosic is broadcast through the air.

**Q: Necesito detector de fuga de agua debajo del cemento**
A: Sorry, the leak detector is tested by ultrasonic. The ultranosic is broadcast through the air. If you want to use it to test the water leak detector under cement, I'm afraid it can't be detected.

**Q: Can you detect a water leak in a pipe under concrete floor?**
A: Sorry, it can't detect under concrete.

**Q: Would this work for low pressure vacuum hose in a car emissions system?**
A: This system works by sending out an ultrasonic frequency sound and using the receiver to pick up this signal.  I used my unit to check for water leaks in my car.  I put the transmitter inside the car near to the leak and used the receiver to check for the generated sound outside and around the door seals of my car.  A leak would require an opening in the car's seals and this should allow the sound to get through to be picked up by the detector.  It is unlikely that the sound that you are interested in would be detected by this unit.

Works well on most leaks. Perfect for what we got it for.

### ⭐ Only Detects what human ear can Hear
*by S***D on May 11, 2025*

I tested the device on my nitrogen tank by simulating a leak. It only detected what was already audible to me. If its detection capability is limited to what I can hear, then I fail to see its value. I spent the entire day yesterday searching for a leak based on my trust in this ineffective tool.
