- Ultra-High Sensitivity & Instant 0.5s Response：Equipped with advanced semiconductor sensors and dual-detection technology (diode heating induction + UV detection), this refrigerant leak detector delivers industry-leading sensitivity of 0.14 oz/year (4g/year) to catch even the smallest refrigerant leaks. With an ultra-fast 0.5-second response time and real-time PPM (0-1000PPM) concentration display on a large backlit LCD screen, it enables instant, no-wait detection so you never miss a leak.
- 30cm 180° Flexible Probe & Durable Design：The 30cm (11.8 inch) extra-long flexible probe bends 180° freely, allowing easy access to hard-to-reach narrow spaces in HVAC systems, car air conditioners, and refrigerators. Encased in a durable PVC sleeve, the probe is rust-resistant for long-term use, while the multi-hole airway design protects internal sensors, ensuring durability and a long service life even in harsh working environments.
- Customizable Threshold Alarm & Multiple Alert Modes：Easily set your desired concentration alarm threshold by long-pressing the SEL button, with adjustable up/down control for precise calibration. When the detected concentration exceeds the set limit, the device triggers clear audible and visual alarms paired with on-screen alerts, eliminating false alarms and ensuring reliable leak notifications. It also features an auto-shutoff function to extend battery life.
- Wide Compatibility & Multi-Purpose Applications：This halogen leak detector is compatible with all halogen refrigerants, including R134a, R22, R32, R410a, and more. It is the perfect tool for a wide range of applications: HVAC system maintenance, automotive air conditioning repair, refrigerator and cold storage inspection, and industrial refrigeration equipment testing, making it a must-have for technicians and DIY enthusiasts alike.
- Strong Anti-Interference & User-Friendly Operation：Built with powerful anti-interference technology, the probe 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.
