The Robinair LD7 Dual Mode Refrigerant Gas Leak Detector features a new color graphic display that highlights leak sizes in two unique ways. Bar graph mode shows the amount of refrigerant detected in the air and changes colors as the sensor gets closer to the leak. Sweep mode allows the user to see the level of refrigerant detected in the air through a line graph that helps the user trace back and forth to pinpoint the exact source of the leak.
The LD7 also uses an audible alarm to alert technicians of a refrigerant leak, UV LED lights to locate leaks using UV dye and an inspection light for searching in dark locations. The LD7 features a patented 3 LED UV light that emits the optimum wavelength for A/C dye fluorescence. The UV light can be used simultaneously with the solid electrolyte sensor or independently.
The LD7 is compatible with most commonly used refrigerants today, including R-134a and 1234yf, and is equipped with a stable, long life sensor that will last up to 10 years. The LD7 features a long life solid electrolyte semiconductor sensor technology that is designed to detect all CFC, HCFC, HFC, and HFO refrigerants including R-1234YF (HFO), R-134A (HFC), R-410A (HFC), R-22 (HCFC), R-407C (HFC), R-507 (HFC), R-12 (CFC), R-404C (HFC). The LD7 is designed to detect all SNAP approved refrigerant blends.
The LD7 meets all of the current industry leak detector standards and is covered by a 2-year warranty. Uses 4 AA batteries, included.
Sweep (Pinpoint) Mode
This mode allows the user to “zero in” or pinpoint hard to find small leaks.
Similar
to an oscilloscope trace “sweeping” across the display, the display “cursor” will sweep across the display from left to right tracking a horizontal baseline over a 3 second period.
When no leak is sensed, the baseline trace will be flat. While searching, if refrigerant gas is
sensed, the horizontal trace on the display will rise up and continue to rise as the leak source is approached. If the user moves away from the leak source, the trace will drop back down.
Because the display in this mode is based on a time period, the previous leak level sensed will
be displayed helping the user to determine where the maximum level of gas is present- thereby pinpointing the source of the leak.
