UNI-T UT171B Multimeter

UNI-T UT171B Multimeter
The UT171 series multimeters are portable multimeters with automatic and manual range switching and 4 3/4 – 4 5/6 digit resolution. The devices belong to the upper middle class, excel in quality design and reliability, and are also suitable for industrial use. They can measure AC/DC voltages and currents, resistance, diode test, continuity test, capacitance, frequency, duty cycle, temperature, 4-20mA current loop, conductivity, VFC, NCV. The devices allow data storage and connection via USB with optical isolation or via Bluetooth.

UNI-T UT171B Multimeter
Unlike the UT171A, the UT171B has a wider range of resistance and capacitance measurement and also measures conductivity (reverse resistance). The display type is VT-WLCD, the data is bright on a dark background. The display range is ± 60000 for voltages, currents, and frequencies and ± 6000 for capacitance measurements. The display includes a 31-part analog bar graph. Refresh rate of 4 to 5 times per second. The fuses are protected by tubular fuses (10A FF 10A H / 1000V fuse (10 x 38mm); mA/µA FF 800mA H / 600V fuse (6 x 32mm)). The device can test its own fuses (without opening the device). The multimeter is powered by a 7.4 V / 1800 mAh lithium battery. The measuring range can be selected automatically or manually. Test cables with CAT III 1000V and CAT IV 600V safety category tips are included.
