1. Detects leaks in refrigerant lines, hospital sterilization equipment (ethylene oxide), 6 circuit interrupter, dry cleaning solvents, and halide suppression systems, with a probe reach of up to 20 cm. 2. Precision stabilized circuitry, low power consumption design, and sensors for extended battery life (50 hours) and adjustable sensitivity to optimize detection accuracy. 3. The WJL6000 Leak Detectors with LED instantly identifies halide refrigerants at adjustable sensitivity, featuring rapid 2 10 second reset time and continuous operation for HVAC systems, laboratories, and industrial maintenance. 4. Operates at 0 to 52°C with automatic calibration, effectively detecting CFCs (R500), HCFCs (R502), HFCs (R134a/R404a), and mixed refrigerants. Use scenarios: HVAC service in commercial buildings: quickly locate leaks in refrigerant lines using the 20 cm probe, with LED indication and adjustable sensitivity to detect small leaks without excessive downtime. Laboratory and industrial maintenance: monitor for halide refrigerants and mixed refrigerants in research, development, and production environments, benefiting from long battery life and continuous operation. Hospital and sterilization facilities: inspect ethylene oxide sterilization equipment (ETO), 6 circuit interrupters, halide suppression systems, and related dry cleaning solvent systems for leaks, ensuring safety and compliance.
