Description
UNI-T UT139C Multimeter
This product comes with a 3-year warranty. The UNI-T UT139C 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. 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), non-contact voltage (NCV) measurement, capacitance measurement, frequency ratio measurement and temperature measurement. The large, clearly laid-out TN LCD display with backlighting ensures better visibility of measured values. The display range is ±6,000, and 9,999 for capacitance and frequency. 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 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 UT139C 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.
