HVAC Refrigerant Leak Detector, AC Halogen Leak Detection
10 sold in last 24 hours
- High-Sensitivity Freon Leak Detector: The GL77A refrigerant leak detector utilizes a premium heat dioxide semiconductor sensor. Boasting a maximum sensitivity of 0.49oz/year (14g/year), it accurately detects a wide range of halogenated refrigerants. Detection for R134a, R1234yf, R410a, R22, R404a, R407c, R454b, R32, and more. (Note: Due to space limitations, the user manual only lists common models, but this device is fully capable of detecting all halogen refrigerants).
- Fast Response with Visual & Audible Alerts: Featuring a 30-second automatic warmup, and built with strong anti-interference technology, the detector delivers error-free, accurate readings even in complex environments. It features a one-button °C/°F switch, automatic power-off, and a simple, intuitive button layout (SEL, APO, °C/°F, Power) for effortless operation. The ergonomic, handheld design ensures comfortable use during long inspection jobs, while the UV light function provides real-time leak visualization for easier leak location.
- High Sensitivity Levels: This HVAC leak detector supports high sensitivity level. It can pinpoint even minor leaks with a probe distance of ≤0.25 inches (0.63 cm) and a moving speed of ≤3 inches/s (75 mm/s). The flexible probe allows for precise detection in hard-to-reach areas, significantly improving troubleshooting efficiency for HVAC and refrigeration systems. Ideal for HVAC maintenance, residential A/C, refrigeration systems, and automotive A/C repair.
- Backlight Display & Smart Features: Designed with a high-brightness LCD screen, the device clearly displays gas concentration, battery status, and alarm indicators for effortless operation. It also includes convenient daily features such as a reset calibration, and auto-power-off.
- Portable HVAC Tool: Powered by 2 x AAA battery(Included). Complete with a user manual, this is a reliable refrigerant leak detection tool for both professional technicians and DIY homeowners.
