MASTERCOOL 55900 Blue Refrigerant Leak Detector

At the heart of this leak detector is a new low power metal oxide gas sensor with superior performance properties such as lower current consumption and sensor longevity. The new sensor is characterized by high sensitivity and fast response upon detecting the presence of extremely small levels of chlorofluorocarbon gases. For this reason, this sensor was selected and integrated into the 55900 Leak Detector.
In addition, a powerful microprocessor was integrated into the design that automatically selects the best operating condition for the sensor to ensure optimum performance throughout the life of the sensor.
Super Sensitive Function allows the unit further sensitizing beyond the standard settings for locating small leaks with gases such as R1234yf and R407C
