About this item

• 【High-Sensitivity Sensor & Inhalation Design】The automotive freon leak detector features an advanced heated diode sensor with 20x higher sensitivity than soap bubbles, offering a maximum sensitivity of 0.05oz/yr(1.5g/a) in stationary state for precise measurements and the ability to detect subtle leaks in various environments, and the probe can be replaced. This HVAC freon leak detector's unique inhalation design ensures faster response times than traditional leak detectors.
• 【Detects All Halogen Refrigerants & Wide Application Range】 The refrigerant leak detector supports the detection of all halogen refrigerants, including HFCs (e.g., R134A, R404A, R125), HCFCs (e.g., R22, R123, R124, R502), CFCs (e.g., R11, R12, R500, R503), HFOs (e.g., R1234ZE, R1234YF) and blends as well as halon gases in fire suppression systems. This refrigerant leak detector is widely used in automotive/home AC repair, refrigerator maintenance, refrigeration equipment testing, and medical equipment and other scenarios.
• 【9-Stage Leak Level Display & 3-Level Adjustable Sensitivity】 The auto ac leak detector sniffer features a high-definition LED display that shows 9 leak levels in real time, providing a clear visual indication of refrigerant leakage severity. With 3 adjustable sensitivity levels (high, medium, low), the ac leak detector adapts to different environments and refrigerant concentrations. High sensitivity detects minor leaks, while low sensitivity avoids false alarms from other gas interferences, ensuring precise detection and cost savings.
• 【Manual/Auto Zeroing & Manual Mute Function】After powering on, the HVAC leak detector enters a warm-up state (≤35 seconds) and automatically zeros. During detection, you can also manually zero at any time (short press "ZERO") to avoid false alarms from environmental changes, ensuring precise and reliable results. Long press "MUTE" to enable silent mode, which persists after restart, long press again to restore sound. Mute function of the HVAC leak detector allows you to focus more on the detection work.
• 【Buzzer Alarm & Sensor Fault Alarm】When the HVAC halogen detector detects a leak source, it emits rapid beeps, and the LED indicator shows the leak level—the higher the number, the more severe the leak. If the sensor is poorly connected or faulty, it also emits rapid beeps, and the LED displays a dash "-". In this case, check or replace the sensor to avoid false or missed detections.
• 【Compact Design, Comfortable Handle & 20-Inch Flexible Probe】The HVAC refrigerant leak detector is made of high-strength industrial plastic, offering impact and drop resistance to protect internal components and extend service life. The ergonomic handle is non-slip and comfortable, reducing hand fatigue during prolonged use. This car refrigerant leak detector is equipped with a 20-inch flexible probe, longer than traditional probes, its flexible design allows easy bending and positioning, making it ideal for complex detection environments.
