H-10 PRO

Ultra-sensitive universal refrigerant leak detector
  • Detects all CFC, HFC and HCFC refrigerants as low as 0.006 oz/yr, including R-410a and R-507
  • Dual power options allow battery operation for the best mobility or wall power for uninterrupted usage
  • Visual and audible indicators include an incremental flashing LED in the probe tip, an internal speaker and a headphone jack
CFC, HFC, HCFC, R12, R22, R134a, R414a, R410a, R502, R507, CFCS, HFCS, HCFCS, R-12, R-22, R-134a, R-414a, R-410a, R-502, R-507

The H-10 PRO is a highly responsive universal refrigerant leak detector using Bacharach’s tried-and-true heated diode sensor technology.  It’s ultra-sensitive to all halogen-based, non-flammable CFC, HFC and HCFC refrigerants for reliable use in a wide range of refrigerant leak detection applications.

The H-10 PRO has a long probe (4.5 ft.) for detecting leaks in hard-to-reach areas, visual and audible indicators to show relative leak sizes and an auto-zeroing feature (automatic mode only) for finding leaks in backgrounds where target gas is present. It has an internal sensor calibration reference to ensure optimum performance and comes with a 3 year warranty.
