UEI RLD15B Refrigerant Leak Detector

The UEi RLD15B is a refrigerant leak detector with a solid electrolyte semiconductor sensor. The RLD15B refrigerant leak detector is designed and certified to meet the new tougher standards and detect the latest refrigerants including, HFC, HCFC, CFC, and SNAP-approved hydrocarbon blends. The heated sensor has a detection sensitivity of .05 oz/year and is designed to increase accuracy, provide a quick response in contaminated or windy environments as well as reduce false alarms.


  • A2L Certified - See Data Sheet Here
  • Solid semiconductor sensor
  • Detects HFCs, CFCs, HCFC refrigerants and blends
  • Sensitivity 0.05 oz/year
  • Mutable beeper
  • Three sensitivity levels
  • Three leak indications (audible, bright flashing LED, and digital leak size)

The UEi RLD15B refrigerant gas leak detector has three sensitivity levels, a visual digital leak size indicator, and an audible alarm. The refrigerant gas leak detector responds audibly and visually to changes in refrigerant concentration. The digital leak indicator remains off until a leak is detected. When detection occurs, the signal is amplified, digitized, and displayed on the front panel as a large, bright red number from 1 to 9 corresponding to the size of the leak. The reading is independent of the selected sensitivity level. When the leak is detected, the frequency of the beeping increases. The beeper can be silenced by pressing the Mute button on the front panel.

The RLD15B has a red LED at the tip of the 17” probe that is a visual of the tick rate. The LED blinks slowly when first turned on (indicating power is on) and increases intensity in the presence of refrigerant. This red LED is bright enough to be visible in full sunlight.

The RLD15B refrigerant leak detector automatically compensates for ambient levels of refrigerant gas. When the refrigerant leak detector indicates a concentration of refrigerant gas, move the probe away from the contaminated area and then bring it back to confirm the leak source. The detector alarm will reset if the probe is held fixed at the source and will only sound if higher gas levels are detected.

The UEI RLD15B includes a leak test vial that lets you verify that it is properly working before searching for a leak. The RLD15B is powered by 4 ‘AA” batteries and has a built-in work light to help illuminate in darker areas.
