The Uni-T UT336A is a compact refrigerant leak detector that uses a sensor based on the negative corona discharge phenomenon. The device offers high sensitivity up to 3 g/year, warms up in just 3 seconds, and allows for 6-level sensitivity adjustment, making it easier to adapt its operation to the location and working conditions. This model is ideal for servicing air conditioning systems, refrigeration systems, refrigerators, and in the automotive industry, while the audible and visual alarms help quickly locate the source of the leak.
Accurate performance and convenient operation
The UT336A detects three main groups of halogenated refrigerants: CFCs, HCFCs, and HFCs, making it suitable for many common service tasks. The auto-reset function upon startup and the zeroing feature make it easy to begin measurements and improve detection accuracy in practice. Additional conveniences include a battery level indicator, mute mode, and auto-off, which help save energy and extend the device’s operating time up to 20 hours.
