WJL6000 Leak Detectors with LED quickly identifies Halide refrigerants at adjustable sensitivity, with a rapid 2 to 10 second reset time and continuous operation for HVAC systems, laboratories, and industrial maintenance. Operates from 0 to 52 C with automatic calibration, effectively detecting CFCs (R500), HCFCs (R502), HFCs (R134a/R404a), and mixed refrigerants. Precision-stabilized circuitry, low power consumption design, and premium sensors deliver extended battery life (50+ hours) and adjustable sensitivity to optimize detection accuracy. Detects leaks in refrigerant lines, hospital sterilization equipment (ethylene oxide), dry cleaning solvents, and halide systems, with a 20 cm probe reach. Applications and use scenarios: - HVAC service and maintenance in commercial buildings - Refrigerant leak surveys in laboratories and research facilities - Industrial plant maintenance, including areas handling halide systems and associated solvents
