- Ultra-High Sensitivity & 0.5s Instant Response：Equipped with advanced semiconductor sensors and dual detection technology (diode heating induction + UV ultraviolet detection), this refrigerant leak detector achieves an industry-leading maximum sensitivity of 0.14oz/yr (4g/yr), capable of catching even the tiniest refrigerant leaks. It delivers an ultra-fast 0.5-second response time, enabling immediate, no-wait detection with real-time PPM (0-1000PPM) concentration display on the large backlit LCD screen, ensuring you never miss a leak.
- 30CM 180° Flexible Probe & Durable Design：The 30CM (11.8 inch) ultra-long flexible probe can be bent 180° freely, allowing you to reach tight, hard-to-access spaces in HVAC systems, car air conditioners, and refrigerators with ease. The probe is wrapped in a durable PVC sleeve for long-term rust-free use, while the porous airway design protects the internal sensors, ensuring durability and long service life even in harsh working environments.
- Customizable Threshold Alarm & Multiple Alert Modes：Long-press the SEL button to easily set your desired concentration alarm threshold, with adjustable up/down controls for precise debugging. When the detected concentration exceeds the set limit, the device triggers a clear sound and light alarm, paired with visual screen alerts, eliminating false alarms and ensuring reliable leak notification. It also features an automatic power-off function to extend battery life.
- Wide Compatibility & Versatile Applications：This halogen leak detector works with all halogen-based refrigerants, including R134a, R22, R32, R410a, and more. It is the perfect tool for a wide range of applications: HVAC system maintenance, automotive air conditioner repair, refrigerator and cold storage inspection, and industrial refrigeration equipment testing, making it an essential tool for technicians and DIYers alike.
- Strong Anti-Interference & User-Friendly Operation：Built with strong anti-interference technology, the detector delivers error-free, accurate readings even in complex environments. It features a one-button ℃/℉ switch, automatic power-off, and a simple, intuitive button layout (SEL, APO, ℃/℉, 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.
