Multimeter UNI-T UT171B

Product detailed description

Multimeter UNI-T UT171B
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.

Multimeter UNI-T UT171B
Unlike the UT171A, the UT171B has a higher range for resistance and capacitance measurements and additionally measures conductivity (inverse of resistance). The display type is VT-WLCD, the readings are bright on a dark background. The display range is ±60000 for voltage, current and frequency measurements and ±6000 for capacitance measurements. The display includes a 31-piece analogue bargraph display. The refresh rate is 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/µA 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. Measurement cables with spikes in safety category CAT III 1000V and CAT IV 600V are included.
