RV 382PR Refrigerant Leak Detector 0.1oz/year

High-precision heated diode sensor: This refrigerant leak detector features a high-precision heated diode sensor with a maximum sensitivity of 3 grams/year (0.1 oz/year). The 30-second warm-up time and automatic self-check function (buzzer and vibration) ensure reliable operation. The sensor's lifespan exceeds 500 hours for long-lasting performance. Smart LCD screen and multi-function control: This HVAC leak detector has a color screen with a bar graph that clearly displays the leak intensity. Three adjustable sensitivity levels (high/medium/low) offer flexible detection. Short press reset to stabilize readings, long press mute to toggle between audible and vibration alerts. Wide refrigerant compatibility (A1/A2L/A3): This Freon leak detector detects CFCs (R12, R502) and HFCs. (R134a, R410a, R404a, R407C) and generation refrigerants including R454B, R290, and R600a. Supports A2L types and complies with evolving regulations for automotive HVAC, refrigeration, and air conditioning systems. Battery powered: This refrigerant detector uses a high-capacity rechargeable battery (not included) for over 7 hours of continuous operation. Low battery alert at 3.5V and automatic shut-off at 3.4V. User-friendly design for efficient work: This AC leak detector features automatic shut-off after 30 minutes of inactivity to conserve power. Built-in leak memory and sensor fault alarm provide increased reliability. The intuitive interface and multifunction controls make it easy for technicians of all skill levels to operate.
