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. In fact, it's the ac leak detector that technicians trust. 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.

• Detects all halogen-based, non-flammable CFC, HFC and HCFC refrigerants including: R12, R22, R134a, R404a, R410a, R502, R507 and many others
