The UNI-T UT139A is a new professional multimeter with True RMS classification and CAT III 600V protection designed for the needs of electricians to measure LV distribution networks in buildings. Innovative and industrial design with protective sleeve ensures impact resistance of the multimeter. The instrument includes a number of extra features such as low impedance voltage measurement (LoZ) (for variants UT139E + UT139S), variable frequency voltage measurement (VFC) (for variants UT139E + UT139S), contactless voltage measurement (NCV). Large and well-arranged LCD TN backlit display ensures better display of measured values. The display range is ± 1999. Refresh rate 2 to 3 times per second. The fuses are protected by tube fuses (range 10A fuse FF 10A H / 600V (6 x 25mm); range mA / µA fuse FF 200mA H / 600V (6 x 32mm)). The multimeter is powered by two AA 1.5V alkaline batteries. The measuring range can be selected automatically or manually. Included are test leads with spikes and batteries.

UT139A is an ideal choice if you want a professionally equipped multimeter with a number of extra features that is also accurate, safe, easy to read and use.
