Description
UNI-T UT139A Multimeter
This product comes with a 3-year warranty. The UNI-T UT139A is a new professional multimeter with True RMS rating and CAT III 600V protection, designed to meet the needs of electricians for measuring JT distribution networks in buildings. The innovative, industrial design with a protective sleeve ensures the multimeter’s impact resistance. The instrument includes a range of additional features, such as low-impedance voltage measurement (LoZ) (for the UT139E + UT139S variants), variable frequency voltage (VFC) measurement (for the UT139E + UT139S variants), and non-contact voltage (NCV) measurement. The large, clearly laid-out backlit TN LCD display ensures better visibility of measured values. The display range is ±1999. 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 200mA H / 600V fuse (6 x 32mm)). The multimeter is powered by two 1.5 V AA alkaline batteries. The measurement 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 functions, which is also accurate, safe, easy to read and use.
