HVAC Refrigerant Leak Detector, Rechargeable Halogen Freon Sniffers, with Ultra-Sensitive Probe, 180° Flexibility & Customizable Alerts for HVAC Maintenance

Ultra-sensitive: This halogen gas detector features solid-state sensors with a heating diode and dual ultraviolet detection technology, achieving a sensitivity of up to 4 g/year to locate even the smallest leaks. The large, backlit LCD screen displays real-time concentration levels (0-1000 ppm) with a fast 0.5-second response time, ensuring no leak goes undetected. 180° flexible probe: The HVAC leak tester includes a 30 cm, 180° flexible probe with a protective PVC housing, allowing easy access to tight areas of AC units, refrigerators, and industrial equipment. Its multi-hole air channel design protects the internal sensor for long-lasting durability in harsh conditions. Customizable alerts: This refrigerant leak detector allows you to set adjustable concentration thresholds with a long press of a button. It triggers synchronized audio-visual alarms and on-screen alerts when levels exceed the limit. while automatic power-off preserves battery life for extended use.
Wide Compatibility: The air conditioning leak detector is suitable for R134a, R22, R32, R410a, and other halogen refrigerants, making it ideal for HVAC maintenance, automotive air conditioning repair, freezer inspections, and industrial refrigeration systems.
Anti-Interference: Designed with robust anti-interference technology, this gas leak tester provides accurate readings in complex environments. Features include one-touch °C/°F switching, an ergonomic handle, and ultraviolet viewing to precisely lock onto the specific leak location.
