Bacharach H-10 Pro 

The Bacharach H 10 Pro leak detector (p/n: 3015-8004) is an ultra-sensitive professional electronic refrigerant leak detector that detects all halogen-based, non-flammable CFCs, HFCs, and HCFCs refrigerants down to leaks as small as 0.006 oz./yr. The dependable heated diode sensor is highly responsive and can track down leaks where other detectors have failed you. The auto-zeroing feature in automatic mode also helps detect leaks in backgrounds where target gas is present. The Bacharach H-10 Pro is the best refrigerant leak detector on the market.


H 10 Pro Bacharach - Key Features


  • Detects all CFC, HFC and HCFC refrigerants as low as 0.06 oz./yr
  • Rechargeable Battery
  • Wall Power Option
  • Visual and audible indicators
  • Probe length of 4.5 ft.
  • Made in the USA




The H 10 Pro refrigerant leak detector sensor uses positive ion emission technology, commonly known as a heated diode. The sensor is extremely sensitive to Freon substances like refrigerants making it highly resistive to false alarming while retaining superior sensitivity for pinpointing the most difficult to find refrigerant leaks.


The pump inside the refrigerant leak detector draws air through the probe to the sensor. The presence of refrigerant(s) causes the Bacharach H-10 Pro leak detector to emit both an audible alert and a visual indication with a flashing LED in the probe tip.


Sensitivity to pinpoint small, medium, and large leaks can be controlled by setting the Leak Size switch. The leak detector also has automatic re-calibration in areas where there is a large amount of refrigerant. This is extremely useful if you are in a cramped space and there is a decently sized leak. The Bacharach H-10 Pro universal refrigerant leak detector recognizes the ambient air and adjusts accordingly to give you the ability to hone in on the higher concentrated pockets of refrigerant.




The Leak Size switch has three settings:

  • Small – is for the highest sensitivity, which will indicate leak rates of 0.006 oz/year or greater for HFC gases like R134a.
  • Medium – is used for Chlorine-based (CFC and HCFC) gases like R12 and R22. This setting will indicate a leak rate of approximately 0.1 oz./year or greater and is useful for locating larger HFC leaks.
  • Large – is used to zero in on large leaks of any refrigerant. The large leak setting should be used in conjunction with manual mode.

The Bacharach H-10 has both an Auto and Manual Mode.

  • The Auto Mode enables the Bacharach H-10 Pro refrigerant leak detector to block out background levels of refrigerants. This greatly reduces and /or eliminates false alarms while retaining sensitivity to quickly locate small or medium size leaks. Pinpointing in this mode requires continuous probe movement.
  • In Manual Mode the auto-zero circuit is disabled and will not zero the leak if the probe is held over the leak site. The manual mode may require more frequent readjustment of the Manual Balance control, but provides greater sensitivity than Auto Mode.


The H-10 Pro refrigerant leak detector is ultra-sensitive and can detect leaks as small as 0.006 oz/year and the 54 inches (4.5 feet) extra-long probe makes it easier to detect leaks in those hard to reach areas or tight spaces.


The Bacharach H-10 heated diode sensor technology has a wide range of applications and is very popular among automotive AC technicians due to the prevalence of really small leaks found on many cars.


The H-10 Pro leak detector is also great for finding leaks in food and beverage production that can eliminate more costly repairs and downtime. The unit is light enough to carry around and includes a shoulder strap for added convenience.


In addition, the refrigerant leak detector has dual power options, the battery option for best mobility or wall power for uninterrupted usage. The leak detector can operate on battery power for about 3 hours on a full charge.


Bacharach offers a 3 year warranty on this refrigerant leak detector and a 1 year warranty for the battery and sensor. The H-10 sensor is rated to have a typical life of roughly 1 year.


The Bacharach H-10 Pro is easily one of the most popular and effective refrigerant leak detectors on the market. Read a Review on A-Z Testers blog.
