Description The UNI-T UT139B 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), capacitor capacitance measurement, frequency ratio
measurement, or temperature measurement. Large and well-arranged LCD TN backlit
display ensures better display of measured values. The display range is ą 4000,
for capacitance and frequency 9999. 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 / ľA fuse FF 500mA 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.
UT139B 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.
