Mastercool 55800 – INTELLASENSE Refrigerant Leak Detector

• Detects all refrigerants (CFC’s, HCFC’s, & HFC’s)
• Unit has been tested and approved to work with R1234yf as well as R32 and R410a
• Progressive LCD with vertical bars corresponding to the magnitude of the detected leak

The 55800 leak detector employs a new metal oxide gas sensor for the detection of chlorofluorocarbon gasses and blends. This tin oxide sensor is characterized by high sensitivity and a fast response, upon detecting the presence of extremely small levels of chlorofluorocarbon gases. Integrated into the design is a powerful microprocessor that automatically selects the best-operating conditions for the sensor, to ensure optimum performance. The optimum sensor performance is maintained and monitored throughout the life of the sensor.

LCD FEATURES:

• WAIT: This indication flashes whenever the unit is in the wait mode. This could occur whenever the unit is turned on or interference is detected
• READY: This indication appears when the unit is ready for use
• INT: This indication appears whenever the microprocessor detects conditions that are not suitable for reliable leak detection. Excessive wind blowing, blocked probe (no air flow), burned out fan, or a missing or defective sensor that needs to be replaced
• BATTERY SYMBOL: When the battery symbol becomes illuminated this is an indication that the battery is low and needs to be replaced
• H – M – L: High, Medium and Low sensitivity ranges will be displayed accordingly based on the selection made on the keypad
• SIGNAL LEVEL BARS: There are 10 vertical signal level bars on the display corresponding to the level of signal detected by the unit
• ERROR SIGNALS: E1 through E9 indicates diagnostic signals

KEYPAD FUNCTIONS:

• ON/OFF: Press the ON/OFF button on the center of the keypad to turn the unit on or off
• VOLUME/MUTE: Press the VOLUME/MUTE button to control the volume of the unit
• H M L SENSITIVITY: Press the H M L SENSITIVITY button to select the desired sensitivity level
• HOLD: Press the HOLD button to freeze the signal bars. Press the HOLD button again to disengage
• PEAK: Press the PEAK button when multiple leaks are suspected as being present
