Here's how to find leaks fast

Refrigerant is heavier than air, so it settles in the A/C system or engine compartment. Start detecting at a low point; a high concentration may not necessarily indicate a leak in that area. Move up as you trace lines. And be sure to check around fittings and connections, and on the underside of lines and components. In windy locations, shield the site to keep the wind from dissipating the refrigerants.

For all CFC, HCFC and HFC Refrigerants

Including R12, R22, and R134a

The first thing you notice about our new electronic leak detector is the modern look. It's been ergonomically designed so it fits your hand. Holding it while you're searching for leaks is natural and comfortable, and you'll find it fits into tight spots so you can thoroughly check for leaks, For all it compact size, the ROB-16600 is packed with features that help you pinpoint leaks quickly.

  • One-Hand Operation The 16" gooseneck probe holds its position so you can operate the detector with one hand.
  • Audible and Visual Leak Indicators An alarm increases in frequency as the tip gets nearer to a high concentration of refrigerant. Also, LEDs indicate a leak, especially helpful for those times when you're working in a noisy environment.
  • Threshold Balancing Control Gives you infinite control for eliminating background contamination so you can zero in on the leak site.
  • Volume Control Adjust the audible leak signal to the volume that's right for the background noise in the shop or at the job site.

Reliable Technology = Dependable Leak Detecting

The ROB-16600 uses proven corona discharge technology to sense leaks. It works by creating a high voltage corona in the sensing tip. When this field is interrupted by refrigerant, the alarm is triggered. All corona discharge leak detectors are not the same, however the quality of key components is critical in providing an effective instrument.


To create the high voltage corona, the unit must "pump-up" from the battery output to 2000 volts. It takes a specialized transformer to consistently provide this voltage, and ours is the result of years of testing and field use to assure operation you can rely on.

Sensing Tip

The materials, shape and finish of the sensor and surrounding shell are critical to the effectiveness and life of the tip. The ROB 16600 is built with a mirror finish and specially engineered tip for superior sensitivity and durability. The tip can be cleaned for even longer life.
