Aituzero Rechargeable Refrigerant Leak Detector, HVAC Freon Leak Detector with Japanese Sensor, 3 Sensitivity Levels, TFT Display, 3 Alarm Modes, AC Gas Sniffer for R134a R410A R22 R1234YF R32 — Open-Box, 5% Off

High-Precision Japanese Sensor & 3 Sensitivity Levels: This refrigerant leak detector is equipped with a high-precision Japanese semiconductor sensor and three sensitivity levels: High, Medium and Low. Adjust the sensitivity based on different leak sizes, working environments and refrigerant concentrations. With sensitivity up to 3g/yr (0.1 oz/yr), this HVAC leak detector helps pinpoint small refrigerant leaks around coils, valves, fittings, service ports and hard-to-reach pipe connections.

3 Alarm Modes & Quick Mute Function: This freon leak detector provides sound alarm, indicator light and vibration alert for clear leak warnings in different jobsite conditions. Each alarm mode can be enabled or disabled independently, giving more flexibility for quiet indoor spaces, noisy HVAC service areas, garages, basements and commercial refrigeration work. The quick mute function helps silence the buzzer while keeping visual or vibration alerts available during leak detection.

Dual Display Views with Real-Time Leak Reading: The full-color TFT display provides clear leak information and real-time PPM readings during AC and refrigeration troubleshooting. Switch between funnel view for quick leak intensity visualization and trend graph view for monitoring leak level changes over time. The easy-to-read display helps track whether the detector is moving closer to or farther from the leak source, improving efficiency for HVAC, auto AC and refrigeration service.

Rechargeable USB-C Battery & Field-Ready Design: Powered by a built-in 2000mAh rechargeable lithium battery, this AC leak detector supports up to 8 hours of continuous use for daily HVAC, auto AC and refrigeration service work. USB-C charging makes recharging simple, while the battery status display and low battery warning help monitor power during use. The rugged handheld housing and 14.5-inch flexible gooseneck probe make it easier to inspect tight spaces around condensers, evaporators, coils, pipes and service ports.

Wide Refrigerant Compatibility for HVAC, Auto AC & Refrigeration: This halogen refrigerant leak detector supports common refrigerants used in residential HVAC, commercial AC, automotive AC repair and refrigeration systems. Compatible refrigerant types include HFC, HCFC, CFC, PFC, HFO, R717 and some mixed halogen refrigerants, including R134a, R410A, R407C, R404A, R22, R123, R32, R502, R503, R-1234YF and more.
