Best Mastercool Refrigerant Leak Detectors

Mastercool, 55800, IntellaSense Refrigerant Electronic Leak Detector With LCD 55800 Includes only: Blow molded case 2 "D" batteries Leak test vial Replacement filters Detects: Combustible Gases Hydrogen Refrigerants: All CFC's, HCFC's and HFC's The 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 with all optional accessories: 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
