WJL6000 Leak Detectors with LED Key benefits Precisionstabilized circuitry for stable, reliable readings. Low power consumption design with sensors for extended battery life (50 hours). LED indicator instantly identifies halide refrigerants with adjustable sensitivity to optimize detection accuracy. Rapid reset time of 2 to 10 seconds and capability for continuous operation in HVAC systems, laboratories, and industrial maintenance. 20 cm probe reach to access hardtoreach areas and detection points. Detects leaks in refrigerant lines, hospital sterilization equipment (ethylene oxides), sixcircuit interruptor, dry cleaning solvents, and halide suppression systems. Essential for HVAC technicians, utility professionals, laboratory researchers, and homeowners needing stable halidebased leak identification in critical environments. Applications and use scenarios Commercial HVAC service: perform routine leak checks in cooling systems, using adjustable sensitivity and the LED feedback to quickly locate and verify leaks. Laboratory and hospital maintenance: inspect halidebased systems and hospital sterilization equipment using ethylene oxide and related setups, including sixcircuit interruptor configurations, with reliable detection and reach from the 20 cm probes. Industrial maintenance: monitor refrigerant lines and halide suppression systems during ongoing operations, benefiting from long battery life and fast reset for efficient field work.
