HVAC Refrigerant Leak Detector, Battery-Powered Halogen Freon Sniffers, with Ultra-Sensitive 180° Flexible Probe & Customizable Alerts

Ultra-sensitive leak detector: This HVAC leak detector combines a semiconductor sensor with diode heating and ultraviolet detection, achieving a sensitivity of up to 4 g/year for extreme accuracy. The large, backlit LCD screen instantly displays concentrations from 0 to 1,000 ppm, while its 0.5-second response time ensures no leak goes undetected. Flexible probe for tight spaces: The 30 cm bendable probe of this refrigerant leak tester rotates 180° to access tight areas of AC units or refrigerators. Its PVC-coated, multi-channel design protects the sensors from damage, ensuring durability in harsh working conditions. Customizable alarm system: This halogen gas detector allows for threshold adjustment via a long press. When leaks exceed set levels, it triggers simultaneous audible, visual, and on-screen alerts while conserving battery power with the shut-off feature. Automatic.
Wide refrigerant compatibility: The Freon leak detector is suitable for R134a, R22, R32, R410a, and other halogen refrigerants, making it ideal for HVAC maintenance, automotive air conditioning repair, industrial refrigeration systems, and appliance testing.
User-friendly operation: Designed with an ergonomic handle and simple controls, this gas leak detector features a Celsius/Fahrenheit switch and ultraviolet display. Its anti-interference structure provides reliable readings even in complex environments.
