Mastercool's hand-held infrared refrigerant leak detector uses an infrared sensor to effectively identify halogenated gases. The ergonomic design and rugged construction provides effortless refrigerant leak detection all while allowing the technician to easily adjust sensitivity to adapt to different environments. This superior IR (infrared) leak detector detects the refrigerant by scanning the area in a slow target scan mode. Moving the sensor back and forth until the alarm sounds; the IR sensor zeros out when held over a leak. This unit provides the same trigger conditions for all refrigerants which is an advantage over other technologies that work better for some refrigerants than others. Packaged in a zippered carry case this kit includes the 55600-A infrared refrigerant leak detector, charging cable and replacement filters.FEATURES:Innovative infrared sensor offers an extended sensor life of 10 yearsEasily select high, medium and low sensitivity levels with a maximum sensitivity up to 0.14 oz/yrSmart sensor technology allows for the selection of popular refrigerants such as R134a, R404a, R407C, R410A and R1234yf with a default setting (ALL REF) that detects all HFC's, HCFC's, CFC's, PFC's and HFO'sAdvanced TFT screen provides clear and easy readings using color graphics that show leakage, sensitivity, battery level and sensor fault indicatorsPeak button indicates the maximum leak detected during measurementsAuto-off function will automatically shut down the unit after 10 minutesDesigned to meet EN14624, SAE1627, SAE2791 and SAE2913 standardsAPPLICATIONS:Responds to all halogenatedResponds to blends such as R410A and R407Detects SF-6 in high voltage circuit breakersDetects halogen gases in fire-extinguishing systemsSPECIFICATIONS:Sensor: UV spectrum absorptionSensor life: 10 yearsAlarm mode: visual and audibleDisplay: high resolution bright TFT active matrix LCDAutomatic shutdown: 10 minutes without operationOperating temperature: -10 to 52°C (14 to 125.6°F)Operating relative humidity: 50% to 85% RHStorage temperature: -20 to 60°C (-4 to 140°F)Probe length: 14.37"Battery: 3.78V 3000mAh lithium battery (rechargeable) (6 hours of detection)
