The Uni-T UT336B refrigerant leak detector is a compact and precise device equipped with a sensitive semiconductor sensor, enabling quick detection of leaks in refrigeration systems. It offers high detection accuracy of up to 3 g/year, 6-level sensitivity adjustment, and audible and visual alarms, ensuring efficient and convenient operation. Thanks to the automatic reset function upon startup and the built-in probe backlight that changes color with the alarm, the user has full control over the measurement even in more challenging conditions. The device supports common refrigerants such as CFCs, HCFCs, and HFCs, making it suitable for air conditioning service, refrigeration equipment repairs, and automotive applications.
Precise detection and quick response
The use of a semiconductor sensor ensures that the device responds quickly and accurately to the presence of a leak. Sensitivity adjustment allows you to tailor the operation to a specific environment, which reduces the risk of false readings and facilitates the detection of even small leaks. As a result, work is more efficient and less time-consuming.
User-friendly design and practical features
The UT336B is designed for everyday use, offering intuitive operation and features such as alarm mute and automatic shut-off. The probe’s built-in backlight improves visibility at the measurement site, and the long battery life—up to 10 hours—allows for comfortable work without frequent interruptions. The robust construction and a probe lifespan of approximately 2 years ensure long-term reliability.
