Refrigerant Compatibility: Detects common refrigerants including R22, R32, R134a. Ideal for air conditioner Freon leak detection, refrigerator maintenance, industrial inspection, and electrical maintenance. Supports cryogen applications.
High-Precision Halogen Sensor: Equipped with a high-sensitivity sensor for R22/R32/R134a (max. sensitivity 0.5 oz/yr or 14g/yr). 30-second preheating with automatic calibration and buzzer/backlight self-check. Built-in 1000mAh rechargeable Li-ion battery with Type-C charging for field use.
Smart Display & Triple Alarm: High-definition color screen (HD02C only) with simulated bar graph shows leak intensity. Triple alarm: buzzer beep + red backlight + screen display. Auto-power-off after 10 minutes inactivity. Adjustable alarm value and sound on/off.
Accurate Leak Detection & False Alarm Reduction: Locate tiny pinhole leaks that soap/dye methods miss. Move probe slowly (<75 mm/s) within 5 mm of surface. Bar graph frequency and buzzer/backlight intensity rise as you approach leak source. Default alarm at 600ppm with adjustable setting.
Long Runtime & Field-Ready Power: 1000mAh 3.7V lithium battery provides continuous operation for extended field work. Low battery warning and automatic shutdown (10 min) protect the device. Type-C charging interface eliminates disposable batteries. Reliable for HVAC technicians.
