56100
“RAPTOR” REFRIGERANT LEAK DETECTOR

Product Description

Professional HVAC Leak Detection Tool with Corona Discharge Sensor

The Mastercool 56100 Raptor Refrigerant Leak Detector is a high-performance diagnostic tool designed for HVAC and automotive professionals who demand fast, accurate, and reliable refrigerant leak detection. Utilizing advanced corona discharge sensor technology and a digital microprocessor, the Raptor delivers instantaneous response and pinpoint accuracy—even for the smallest leaks.

Compatible with all major refrigerants including CFCs, HCFCs, HFCs, and blends (R134a, R410A, R22), this detector is ideal for servicing modern and legacy systems.

  Detects all common refrigerants quickly and reliably
• High Sensitivity Detection (1/10 oz/year)
  Identifies even the smallest leaks with precision
• 3 Adjustable Sensitivity Levels (5 Detection Levels)
  Customize detection based on environment and leak size
• LED + Audible Alert System
  Visual leak level indicator combined with variable-frequency sound for easy pinpointing
• Reset Function for Accuracy
  Isolates higher concentration leaks for precise diagnostics
• Flexible 16-Inch Probe
  Access tight, hard-to-reach areas in HVAC and automotive systems
• Tronic Keypad Controls
  Easy adjustment of sensitivity, reset, and battery check functions
• Replaceable Sensor Tip (Part #55100-SEN)
  Extend tool life and maintain performance
• Portable Kit Included
  Comes in a blow-molded case with UV glasses, batteries, and sensor tip

APPLICATIONS:
The Raptor Leak Detector is perfect for:

• HVAC System Diagnostics – Residential and commercial air conditioning
• Automotive A/C Repair – Detect leaks in vehicle refrigerant systems
• Refrigeration Systems – Maintenance of cooling units and compressors
• Industrial Cooling Equipment – Leak detection in large-scale systems

SPECIFICATIONS:

• Sensor Type: Corona Discharge
• Sensitivity: Detects leaks as small as 1/10 oz/year
• Detection Capability: CFCs, HCFCs, HFCs, and blends
• Sensitivity Levels: 3 (with 5 detection levels)
• Probe Length: 16 inches (43 cm)
• Power Supply: 2 “C” batteries (included)
• Compliance: Meets and exceeds SAE J1627
• Sensor Replacement: 55100-SEN (included)

HOW IT WORKS:
The Raptor uses a digital signal microprocessor to analyze changes in refrigerant concentration. When a leak is detected:

• The LED bar graph increases to indicate leak intensity
• The audible alarm frequency rises as concentration increases
• The RESET function allows you to ignore background levels and focus on the exact leak source

IMPORTANT LEAK DETECTION TIPS:
Turn Off the System Before Inspection

• Ensure the system is OFF before testing
• Maintain at least 50 PSI pressure at 60°F+ for accurate detection

Use Proper Probe Technique

• Move probe at 1–2 inches per second
• Keep probe about 1/4 inch from the surface
• Use fresh air and reset function to confirm leak location

Handling Humidity & Contaminants

• Allow the unit to stabilize in high humidity environments
• Use RESET to recalibrate in contaminated areas

WHAT’S INCLUDED:

• Mastercool 56100 Raptor Leak Detector
• Replaceable sensor tip (55100-SEN)
• 2 “C” batteries
• Blow-molded carrying case

Built for Accuracy. Designed for Professionals.

If you need a reliable, easy-to-use refrigerant leak detector that delivers fast and precise results, the Mastercool 56100 Raptor is the tool you can trust for every job.
