UNI-T UT336A Refrigerant Leak Detector

The UNI-T UT336A is a professional refrigerant leak detector designed for HVAC technicians and service professionals. It utilizes a heated diode sensor to detect a wide range of refrigerants including CFCs, HCFCs, HFCs, and HFOs such as R12, R22, R134a, R404a, R410a, and R1234yf. With a minimum leak rate sensitivity of less than 3g/year for R134a, it ensures precise and reliable leak detection.

Advantages

The UT336A features three sensitivity levels (High, Medium, Low) for versatile detection, an audible buzzer and visual LED bar graph for clear alarm indication, and automatic background compensation for stable operation. Its flexible 30 cm probe allows access to tight spaces, and the durable ABS plastic housing ensures longevity in demanding environments.
