UNI-T UT139A Multimeter

UNI-T UT139A Multimeter
This product comes with a 3-year warranty. The UNI-T UT139A is a new professional multimeter with True RMS classification and CAT III 600V protection designed for electricians' needs to measure JT distribution networks in buildings. The innovative, industrial design with protective sleeve ensures the multimeter's impact resistance. The instrument includes a number of additional features, such as low impedance voltage measurement (LoZ) (for UT139E + UT139S variants), variable frequency voltage measurement (VFC) (for UT139E + UT139S variants), and non-contact voltage measurement (NCV). The large, well-arranged TN LCD display with backlighting ensures better display of measured values. The display range is ± 1999. Refresh rate of 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 200mA H / 600V fuse (6 x 32mm)). The multimeter is powered by two 1.5 V AA alkaline batteries. The measuring range can be selected automatically or manually. Test leads with tips and batteries are included.

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