Amprobe TMULD-300 Ultrasonic Leak Detector with Transmitter – Best Overall Ultrasonic Leak Detector

Amprobe TMULD-300 Ultrasonic Leak Detector with Transmitter
  • Senses pressurized leaks, detects electrical arcing, and finds failing solenoids, valves, and bearings
  • Comes with a transmitter that emits an ultrasonic frequency to help locate leaks that are not pressurized enough to emit frequencies the detector can pick up
  • Ultrasonic sensor converts ultrasonic frequencies to an audible range so they can be heard
  • Detects any pressurized leaking gas, including chlorofluorocarbon (CFCs), hydrofluorocarbon (HFCs), nitrogen (N), carbon dioxide (CO2), and steam
  • Parabola horn aids leak detection from a distance and in noisy areas
  • Tests the "air-tightness" of weather seals, tanks, ovens, refrigerators, etc.
  • Locating leaks in duct work
  • Finds the ends of buried PVC pipes
  • Detects any pressurized gas leak regardless of type CFC's, HFC's, Nitrogen, etc. (unaffected by contaminants)
  • Transmits an ultrasonic signal for non pressurized applications

Inficon Ultrasonic Leak Detector – Best under $500

Inficon Ultrasonic Leak Detector
  • Made in: United States
  • Commercial brand: Inficon
  • Test Instruments & Gauges

ALLOSUN Ultrasonic Leak Detector & Transmitter Air Water Dust Leak – Best under $100

ALLOSUN Ultrasonic Leak Detector & Transmitter Air Water Dust Leak
  • Power supplied by 2 pieces 9V, 6F22 battery.(Battery not provided by seller)
  • Quick and simple location of air,water, dust leaks.
  • Place the transmitter in the vehicle and close the doors and windows.
  • Trace the detector around outside of the screen, windows and door seals to locate the leak.
  • Includes adjustable headphone for detector.

Amprobe ULD-300 Ultrasonic Leak Detector

Amprobe ULD-300 Ultrasonic Leak Detector
  • Senses pressurized leaks, detects electrical arcing, and finds failing solenoids, valves, and bearings
  • Ultrasonic sensor converts ultrasonic frequencies to an audible range so they can be heard
  • Detects any pressurized leaking gas, including chlorofluorocarbon (CFCs), hydrofluorocarbon (HFCs), nitrogen (N), carbon dioxide (CO2), and steam
  • Parabola horn aids leak detection from a distance and in noisy areas
  • Extension tube provides additional reach for access to remote leaks

Leak Detection Tools,Ultrasonic Leak Detector & Transmitter with Headphone Accessory – Best Budget Ultrasonic Leak Detector

Leak Detection Tools,Ultrasonic Leak Detector & Transmitter with Headphone Accessory
  • Located the leak location: Because the sound frequency of the leak port is different from other places, it quickly determine the leak port, suitable for all types of pressure or vacuum system gases.
  • Check the degree of sealing: Adopt the advanced ultrasonic sensor technology to detect leaks of steam and liquid , detect the sealing degree of closed parts, such as cabins, car cockpits, refrigerators and containers.
  • Two measurement methods: real-time detection that EM282-R detects leak port by the sound frequency; And non-real-time detection is that EM282-R capture the frequency signal from EM282-T. If there is gas in the pipe or tank, use real-time detection, or use non-real-time detection
  • Adjustable sensitivity, frequency response: 40KHz±2KHz, adapt to various degrees of leakage, easy to detect and improve measurement accuracy.
  • Ultrasonic testing, fast and accurate, simple to use, green and environmentally friendly. With headphones, indicator lights, beginners can also quickly learn to use.
