LS790B | Refrigerant Leak Detector

10 sensitivity ranges enable the LS790B to detect all non-combustible CFC, HCFC, HFC gases and blends.

Combines the most advanced microcomputer circuitry with field proven Ion-pump sensor technology creating a 
highly sensitive, accurate electronic refrigerant leak detector. Over 100 computer generated tones and a high 
intensity bar graph display quickly alerts the user to varying halogen concentrations. Patented automatic calibration 
design eliminates the need for manual balance or tick rate adjustments while the user selectable 10 sensitivity 
ranges enables the LS790B to detect all non-combustible CFC, HCFC, HFC gases and blends.

Key Features

• 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 optimal performance at all times

Testimonials
“LS790B is the best leak detector I’ve owned. This leak detector will pick up the smallest of leaks with no effort on 
my part. The alarm sounds funny, but man this thing works. I’m not going to use my old leak detector anymore after 
buying this CPS leak detector.”
