Product Description

From the Manufacturer

CPS Products Electronic Refrigerant Leak Detector is designed to ensure efficient leak detection. It features a patented Ion-Pump sensor with built-in selective filter housing and includes a high intensity bar graph display.

Product Description

CSLS790B Features: -Patented Ion-Pump sensor with built-in selective filter housing.-0.25oz/yr (7g/yr) leak rate of HFC..-10 high intensity bar graph display.-R12 and R134a Deluxe Leak Seeker® Detector. Options: -Over 100 computer generated tones varying in intensity with leak size. Specifications: -Lock-out modeThe LS790B Leak-Seeker® 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 carying 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 refrigerants. Lock out mode is a unique feature that enables quick and easy locating of refrigerant leaks in highly contaminated search zones.  In this mode, the unit will automatically and systematically store the recorded concentration levels of background refrigerant while initiating leak search, alarming only in the area of highest recorded concentration level, the actual leak source. Operating temp: 0 to 140F / -18 to 60C. 40 hours battery life using 4 "AA" alkaline batteries.  Auto OFF after 15 minutes of inactivity. . Warranty: -2 yr warranty on material and workmanship.

This is the best leak detector I have owned. It is really sensitive to small leaks. I owned a Inficon leak detector and it does not even compare to this CPSLS790B leak detector. This CPs detector will pick up the smallest leaks with no effort. The only thing I do not like about it is the alarm sound has a funny sound to it. But man this thing works. I'm not going to use my old Inficon leak detector no more after buying this CPS tool. CPS is much better. I don't think this detector does the new refrigerants. Not 100% sure on this but I believe I'm correct. Research this to be sure. I no it does R22 and R12. I would buy another one .

It works good for the price paid, and helped me find a leak in my tractor's A/C. I wish it was a bit easier to use, but after reading the directions a couple times, it finally made sense. 4 star product, good value for the price, but I knocked it down a star, for the sketchy instructions.

I took this detector to the Philippines to find a leak on my Hyundai Starex Van because none of the AC service centers have any updated equipment. With in 5 minutes I found the high side line had a leaky schrader valve even thought no oil or residue was showing. Replaced the valve and now almost 1 year and no issues with the AC.

Strangely enough, was shipped the more expensive LS780C, in a box labelled as LS790B (and the unit's serial number matches the box). Works as expected, but have to move slowly along lines. Very sensitive (oil based anti-rust spray sets it off, as does the insulating foam under the dash) - BUT it did find a leak, and I was able to fix it. The sensor tip worked itself loose and started giving me full alarms every 5 seconds - until I tightened the tip (then all good). VERY useful tool, but for very slow leaks (emptying in a year), I recommend combining with UV dye, and maybe even some pro-active aging seal replacement.
