Description
UNI-T UT139S Multimeter
This product comes with a 3-year warranty. The UT139S is a new professional multimeter with True RMS rating and CAT III 600V protection, designed to meet the needs of electricians for measuring LV distribution networks in buildings, featuring a black EBTN display. The device is cETLus certified and includes a range of additional features, such as low-impedance voltage measurement (LoZ), non-contact voltage measurement (NCV), capacitance measurement and temperature measurement. A clear display with a 31-segment analogue line simulation ensures better readability of measured values and improved visual representation. The data on the display is shown against a dark background, unlike the UT139E, which displays dark data against a light background; otherwise, the two devices are exactly the same. The display range is ±9.999 for capacitance and frequency measurements and ±5.999 for other measurements. The refresh rate is 2 to 3 times per second. The fuses are protected by tubular fuses (10A FF 10A H / 600V fuse (6 x 25mm); mA / µA FF 600mA H / 600V fuse (6 x 32mm)). The multimeter is powered by two 1.5V AA alkaline batteries. The measurement range can be selected automatically or manually. Test leads with tips, a type K thermocouple and batteries are included.
The UT139S is the ideal choice if you want a professionally equipped multimeter with a range of premium features, which is also accurate, clear, safe and very easy to use.
