Operation

1. Power on the Intellasense leak detector
2. Allow sensor to warm up and auto-zero to ambient conditions
3. Select appropriate sensitivity level (1, 2, or 3)
4. Move probe tip slowly around suspected leak areas (fittings, connections, hoses)
5. Listen for increasing tick rate and watch LED indicators
6. When leak is detected, tick rate increases and LED illuminates
7. Pinpoint exact leak location by moving probe slowly
8. Mark leak location for repair
9. Verify repair by re-testing after service

Leak Detection Best Practices

• Start with Low Sensitivity: Use level 1 in contaminated environments, increase as needed
• Move Probe Slowly: Allow sensor time to respond to refrigerant presence
• Check Common Leak Points: Fittings, connections, hoses, Schrader valves, compressor seals
• Use Headphones: In noisy workshop environments for better audible detection
• Allow Warm-Up Time: Sensor performs best after brief warm-up period
• Keep Probe Clean: Wipe probe tip regularly to maintain sensitivity
• Test in Clean Air: Move away from leak area periodically to allow sensor to reset

Maintenance

• Sensor Replacement: Replace sensor when sensitivity decreases (typically after extended use)
• Probe Care: Keep probe clean and free from damage
• Storage: Store in protective case in clean, dry environment
• Battery Maintenance: Replace batteries as needed or use mains power
• Regular Testing: Test detector response periodically with leak test vial
• Keep Clean: Wipe exterior and probe regularly

Why Electronic Leak Detection?

Electronic leak detectors like the Intellasense offer significant advantages over traditional methods:

• High Sensitivity: Detects smaller leaks than bubble solutions or UV dyes
• Immediate Results: No waiting for dye circulation or bubble formation
• Pinpoint Accuracy: Locates exact leak source quickly
• Clean Method: No messy dyes or solutions
• Professional Standard: Industry-standard method for leak detection
• Cost-Effective: Saves time and reduces diagnostic costs
• Versatile: Works with all refrigerants and system types

R1234yf Leak Detection Requirements

R1234yf is a mildly flammable refrigerant used in modern vehicles. Professional leak detection is essential because:

• Safety: Mildly flammable refrigerant requires careful handling
• Cost: R1234yf is expensive - even small leaks waste costly refrigerant
• Environmental: Leak detection prevents refrigerant emissions
• System Performance: Leaks reduce A/C performance and efficiency
• Standards Compliance: SAE J2913 requires approved leak detectors for R1234yf service

The Intellasense 55800 meets SAE J2913 requirements for R1234yf leak detection, making it suitable for professional automotive A/C service.

Metal Oxide Sensor Advantages

Metal oxide sensors offer several benefits for refrigerant leak detection:

• Multi-Refrigerant: Responds to all common refrigerants
• High Sensitivity: Detects very small leaks
• Fast Response: Quick detection speeds up diagnostics
• Durable: Long sensor life with proper care
• Reliable: Consistent performance in workshop environments
