Multimeter UNI-T UT139A

Product detailed description

Multimeter UNI-T UT139A
We offer a 3-year warranty on this product.

The UNI-T UT139A multimeter is a new professional multimeter with True RMS classification and CAT III 600V protection, designed to meet the needs of electricians for the measurement of LV distribution networks in buildings. The innovative and industrial design with protective housing guarantees the multimeter's impact resistance. The instrument includes a number of superior functions such as low impedance voltage measurement (LoZ) (for UT139E + UT139S variant), variable frequency voltage measurement (VFC) (for UT139E + UT139S variant), non-contact voltage measurement (NCV). The large and clear LCD TN backlit display ensures a more perfect display of the measured values. The display display range is ± 1999. Refresh rate 2 to 3 times per second. Fusing of current ranges is performed by tubular fuses (10A range by FF 10A H/600V fuse (6 x 25mm); mA/uA range by FF 200mA H/600V fuse (6 x 32mm)). The power supply of the multimeter is provided by two AA 1.5 alkaline batteries. The range of measurement quantities can be selected automatically, also manually. Measurement cables with tips and batteries are included.

The UT139A is the ideal choice if you want a professionally equipped multimeter with a range of superior features that is also accurate, clear, safe and very easy to use.
