MASTERCOOL 55900 Intellasense II Refrigerant Leak Detector with Heated Tin Oxide Sensor

The MASTERCOOL 55900 is a next-generation Intellasense II Refrigerant Leak Detector equipped with a low-power heated metal oxide sensor and advanced microprocessor control for consistent, high-sensitivity performance. It detects all common refrigerants (CFCs, HCFCs, HFCs, and blends), including R1234yf and R407C, with a fast response time of less than one second.

Key Features:

• Low-power heated tin oxide sensor delivers high accuracy with 2000-hour lifespan
• Detects all refrigerants, including CFCs, HCFCs, HFCs, and blends
• Intelligent probe tip adapts to environmental conditions to reduce false alarms
• 15.5″ flexible probe reaches tight or obstructed areas
• 6 vertical LEDs indicate signal strength, sensitivity range, and system status
• Peak hold function isolates the largest leak in multi-leak environments
• HR/LR mode switching for broad or focused leak detection
• Microprocessor automatically adjusts to optimal sensor settings
• Three sensitivity levels:
  • High ≥ 0.15 oz/yr (4 g/yr)
  • Medium ≥ 0.25 oz/yr (7 g/yr)
  • Low ≥ 0.50 oz/yr (14 g/yr)
