NITROGEN/HYDROGEN ELEC LEAK DETCTION SYS - FJC

Part #: FJ5109

The FJC FJ5109 Nitrogen/Hydrogen Electronic Leak Detection System is a professional-grade solution engineered for precise and efficient leak detection in automotive and industrial HVAC/refrigeration systems. Utilizing a safe, non-flammable blend of 95% nitrogen and 5% hydrogen (forming gas), this system offers superior accuracy in pinpointing even the smallest leaks that traditional methods often miss. It is an indispensable tool for technicians seeking reliable diagnostics and cost-effective repairs.

Key Features

  • Advanced Sensor Technology: Equipped with highly sensitive sensors designed to detect hydrogen at levels as low as 5 ppm, ensuring the precise identification of leak points.
  • Universal Refrigerant Compatibility: Certified compliant with SAE J2790, this system is compatible with both R-134a and R-1234yf automotive A/C refrigerant systems.
  • Complete Kit: Includes a deluxe H2/N2 leak detector, a 96” red service hose, an H2/N2 regulator with 2” delivery and contents gauges, and both R-134a and R-1234yf manual couplers for comprehensive functionality.
  • Enhanced Leak Detection: Hydrogen's extremely small molecular size allows it to penetrate micro-leaks, providing superior detection capabilities compared to methods like UV dye or nitrogen-only pressure tests.
  • Safety and Environmental Responsibility: The nitrogen/hydrogen tracer gas mixture is non-toxic, non-flammable, non-corrosive, and environmentally safe, ensuring a safer working environment.
  • Durable and Portable Design: Housed in a protective plastic carrying case, the system features a durable, lightweight construction for ease of transport and field use.

Applications

This FJC Nitrogen/Hydrogen Electronic Leak Detection System is ideal for professional technicians in various settings. It excels in diagnosing leaks in automotive air conditioning systems, including those in EV and hybrid vehicles, where traditional methods may be unsuitable. Beyond automotive, it is highly effective for leak detection in commercial and industrial HVAC, refrigeration units, and any pressure-tested system where a tracer gas is required to locate leaks quickly and accurately. This system facilitates pre-fill leak checks, post-repair verification, and routine maintenance to prevent costly refrigerant loss and system damage.
