R-12 & R-134a Deluxe Leak Seeker Detector

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.

Variable Sensitivity: The only portable refrigerant leak detector with 10 different sensitivity ranges for effectively locating all refrigerants, large or small. At the lowest sensitivity setting, the LS790a can detect an HFC-134a leak as small as 1/2oz. (15grams) per year. At the highest sensitivity setting, the unit can detect an HFC-134a leak as small as 1/4oz. (10grams) per year.

Clear: Clears the memory in the microcomputer and recalibrates to ambient.

Lock-Out: Selects Lock-Out mode; measuring and recording the highest level detected by the Ion-Pump. The alarm sounds a two-tone signal and the visual display flashes when the recorded high has been detected, "locking out" all background contamination.

Alarm Select: Selects audible alarm, visual indicator, or both.

Visual Indicator: 10 position moving LED display indicates varying halogen concentrations. As the concentration increases, the LED moves left to right. In the Lock-Out mode of operation, the LED s flash only at the leak source.

Low Battery Indicator: The low battery LED constantly illuminates at half brightness when batteries are low. 18"

Flexible Probe: The metal cable probe easily twists and turns into otherwise inaccessible areas. You re in and out in less time, with no coiled cord to tangle.

Power Saver: Automatically switches power off after 15 minutes of use. Extends battery life.

Super-Sensitive Ion Pump: No moving parts, valves or fans. Provides an extremely precise flow of air through the sensor chamber. The only field replaceable Ion-pump sensor in the industry.
