Multimeter UNI-T UT139E
UT139E is a new professional multimeter with true RMS specification and CAT III 600V protection designed for the needs of electricians. The device meets cETLus certification and includes a number of extra features such as low impedance voltage (LoZ), non-contact Voltage Measurement (NCV), capacitance measurement for capacitors, or temperature Measurement. The 31-segment analog line ensures a better display of the measured values and improved visual representation. The display readings are dark on a light background, unlike the UT139S, where the readings are bright on a dark background, otherwise the two are exactly the same. The display range is ± 9,999 for capacitance and frequency measurements and ± 5,999 for other measurements. 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 600mA 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. The package includes measuring cables with tips, a thermal probe with a K-cell, and a battery.
UT139E 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.
