• Detects all non-combustible CFC, HCFC, HFC, SF6 gases and blends.
• Individually calibrated to detect a leak rate of better than 0.25 oz/yr (7g/yr) of HFC
• Patented Ion-Pump sensor technology proven effective in detecting all refrigerant types
• Patented water vapor filter provides greater stability under high humidity conditions
• Patented automatic calibration circuit ensures peak performance at all times

The LS790B is a perfect combination of advanced micro-processor driven circuitry and field practical features. Developed from over 20 years of engineering experience and sensor research, the LS790B incorporates 3 sophisticated patented technologies to create the world's most advanced, yet easy to use, refrigerant leak detector available today.

The quick and accurate location of a refrigerant leak is critical to the thousands of professionals who rely on MAC for their leak testing needs. Designed to effectively detect all CFC, HFC, HCFC refrigerants and refrigerant blends, the LS790B remains extremely versatile, even with today's rapid introduction of new refrigerants. A range of ten sensitivity settings and patented sensing circuitry virtually guarantees location of any refrigerant leak of any size.

The portability of the LS790B allows the user access to any suspected leak area, no matter how remote or restricted it may be. An ergonomically shaped body provides a sure grip while the 18" flexible probe bends and twists its way into almost any position. A multitude of other time saving and practical features pro- vides the professional with the absolute feedback they need to confidently say, "the leak is here"!.
