The Sun Leak Detector is an essential tool for any service shop or technican, dealing with airconditioning equipment. It offers you a unique combination of state-of-the-art microcumputer circuitry, the most advanced corona discharge sensor and a combination of operational features designed with the airconditioning technician in mind. The result is a professional service tool that is reliable, versatile and effective for all CFC, HCFC refrigerants as well as the new generation of non-ozone depleting refrigerants. The SLD 5550 is effective for: R-134a R-12 R-22 R-502 R-123 |
The SLD 5550 incorporates a fixed normal sensitivity which is automatically selected when the instrument is turned on. This level of sensitivity is adequate for locating most leaks. A digitally selected sensitivity adjustment is also offered. By pressing the SENSITIVITY key, any one of ten sensitivity levels can be selected, allowing leaks less than 1/2 ounce (15 grams) per year of HFC-134a to be detected.
The exclusive LOCK-OUT mode of operation is offered to allow easy detection and pinpointing of a leak in the presence of background contamination. This new and unique concept measures and records the highest concentration of refrigerant detected by the lon-Pump, and automatically ignores or "Locks-Out"concentrations of refrigerants less than the highest, systematically eliminating all background contamination and sounding a distinctive two-tone alarm only at the source of the leak.
To save battery power, an automatic power-off switch is featured which will turn the instrument off after approximately 15 minutes of operation. A low battery indicator alerts the user when batteries need replacement.
With its custom microcomputer, the SLD 5550 is fully temperature, drift, and gain compensated, providing consistent and reliable operation under all environmental conditions.
