GENERAL SPECIFICATIONS
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 sus-
pected 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 posi-
tion. 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"!
