Multimeter UNI-T UT171C

Product detailed description

Multimeter UNI-T UT171C
The UT171 series of multimeters are handheld multimeters with both automatic and manual range switching and 4 3/4 - 4 5/6 digit resolution. The instruments are in the upper mid-range, excellent in quality and reliability and are also suitable for industrial use. They can measure AC/DC voltages and currents, resistance, diode test, continuity test, capacitance, frequency, inverting, temperature, 4-20mA current loop, conductivity, VFC, NCV. The instruments allow data storage and connectivity via USB with optical separation, or via Bluetooth.

The UNI-T UT171C multimeter is the best instrument in the UT171 series.
Unlike the UT171A, the UT171C has a higher range for resistance and capacitance measurements and additionally measures conductivity (inverse of resistance). The display type is OLED with dot matrix. The display range is ±60000 for voltage, current and frequency measurements and ±6000 for capacitance measurements. The display includes an analogue bargraph display with 31 parts. Refresh rate 4 to 5 times per second. Fusing of current ranges is performed by tubular fuses (10A range by FF 10A H/1000V fuse (10 x 38mm); mA/uA range by FF 800mA H/600V fuse (6 x 32mm)). The instrument can test its own fuses (without opening the instrument). The power supply of the multimeter is made by a 7.4V / 1800mAh lithium battery. The range of measurement quantities can be selected automatically, also manually. Included in the package are measuring cables with spikes in safety category CAT III 1000V and CAT IV 600V.
