Check the listing for details. 55800 MASTERCOOL Intellasense Refrigerant Leak Detector. Condition: Brand New. Listed at 653.60 USD. MASTERCOOL Intellasense Refrigerant Leak Detector 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. Technical Features SENSITIVITY: HIGH ≥ 0.15 oz/yr (4.25 g/yr) MEDIUM ≥ 0.25 oz/yr (7 g/yr) LOW ≥ 0.5 oz/yr (14 g/yr) PROBE: Intelligent tip design that senses the condition of the environment, to eliminate the potential of false alarms. Flexible 16” probe for difficult to reach locations DISPLAY: Progressive LCD with vertical bars corresponding to the magnitude of the detected leak Visual indication of the selected sensitivity range REFRIGERANTS: 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 SENSOR LIFE: 2000 hours OPERATING TEMPERATURE RANGE: 0 to 140˚F POWER: Two (2) D Batteries BATTERY LIFE: 60 hours continuous use WEIGHT: 1 lb. 8 oz Please open the battery cover and remove the insulation sheet Package Included 1 X LEAK TEST VIAL 1 X 2"D" BATTERIES 3 X REPLACEMENT FILTERS 1 X BLOW MOLDED PLASTIC BOX 1 X SENSOR PROTECTOR Applicable to all halogen refrigerants, including but not limited to CFCs: Such as R12, R11, R500, R503 HCFCs: Such as R22, R123, R124, R502 HFCs: Such as R134a, R404a, R410a, R407C, R32 HCs: Such as R600a, R290 HFOs: Such as R1234YF Trouble Guide The unit will not power up The unit powers up briefly then shuts OFF The unit alarms continuously without stopping E2 Code Appears on LCD E8 Code Appears on LCD E9 Code Appears on LCD Parameters Sensor Type: Heated Tin Oxide Element Applicable refrigerant: CFC, HFC, HCFC and blends Minimum detectable leakage: ≥0.50 oz/yr (14 g/yr) Sensor lifetime: ≥2000 hours Reaction time: ≤1s Reset: Automatic/manual Warm-up time: 30s Probe length: 16.5 in/420mm Reset time: 10s Package size: 12.3oz/ 350g Working temperature range: 0-50℃ Battery life: 7 hours Working Humidity Range:
