The Mastercool 55800 is a highly sensitive refrigerant leak detector that uses a metal oxide gas sensor for the detection of CFCs, HCFCs and HFCs refrigerants. This Intellasense leak detector has a powerful microprocessor that will automatically select the best operating conditions for the sensor to optimize its performance. The Mastercool refrigerant leak detector is ideal for the service technician looking to locate a leak in a residential or commercial HVAC system as well as an automotive refrigeration system.
Key Features:
- Detects combustible gases, hydrogen, all CFCs, HCFCs, and HFCs refrigerants
- Sensitivity: High 0.05 oz. /year; Medium 0.25 oz. / year; Low 0.5 oz. / year
- Test and approved to work with R123ryf, R32, and R410a
- Sensor life: 2000 hours
- Certified by ACSI to meet SAE J2791, J2913 & EN14624
This refrigerant leak detector can detect leaks that ranges from 0.5 oz. /year on low sensitivity to 0.05 oz. /year on the high sensitivity level. When locating a leak, the technician can easily switch from one level of sensitivity by pressing the H M L Sensitivity button on the keypad. The unit also has an F mode “Super Sensitive Function” that allows a greater sensitivity beyond the standard setting for locating small leaks with gasses such as R1234yf and R407C.
The leak detector’s keypad allows the technician to select the sensitivity level, to control the unit’s beep volume, a HOLD button, and a PEAK button. The HOLD button retains the visual indication of a leak when it is being used in hard to reach locations, and the PEAK button is helpful for identify the largest leak when a system has multiple leaks.
The instrument’s LCD screen provides the technician a variety of information including the readiness status of the unit, sensitivity level selected, error signals, and a visual indication of the concentration of refrigerant gases detected.
The refrigerant leak detector’s 16” probe has an intelligent tip design that senses the environmental conditions to eliminate possible false alarms. The 55800 is operated by 2 “D” batteries with a low battery indicator on the LCD screen. The sensor has a life expectancy of about 2000 hours and the detector comes with a leak test vial to test that the leak detector is working properly.
