UNI-T UT171C Industrial True RMS Digital Multimeters

UNI-T UT171C Industrial True RMS Digital Multimeters

The UNI-T  UT171C is a robust, industrial‑grade True RMS digital multimeter designed for professional troubleshooting and maintenance in demanding environments. Its high‑contrast OLED display delivers 9,999 counts and a 31‑segment analog bargraph, ensuring clear readings even at extreme angles and low temperatures. The unit measures DC and AC voltages up to 1,000 V, and currents up to 10 A, with True RMS accuracy across all ranges. An auto/manual ranging system and a built‑in square‑wave output facilitate rapid diagnostics of industrial control signals, while the low‑impedance (LoZ) ACV mode effectively suppresses ghost voltages on large capacitors.

Beyond basic voltage and current measurements, the UT171C offers a comprehensive suite of functions tailored to industrial applications. Resistance readings span up to 40 MΩ, admittance to 60 nS, capacitance up to 60 mF, and frequency from 10 Hz to 10 MHz. Temperature measurements cover –40 ℃ to 1,000 ℃ (–40 ℉ to 1,832 ℉) via the included point‑contact probe. The meter’s additional capabilities include diode testing, continuity buzzer, duty‑cycle analysis, non‑contact voltage (NCV) detection, relative mode, data hold, and MAX/MIN recording. All inputs feature robust protection circuitry, and DCV ranges present an input impedance ≥10 MΩ to minimize circuit loading.

Designed for seamless integration into modern workflows, the UT171C comes equipped with a rechargeable 7.4 V, 2,000 mAh Li‑ion battery, USB and Bluetooth communication interfaces, and PC software (via CD) for data logging and analysis. When paired with the UT‑D07A Bluetooth adapter and the free “iDMM” smartphone app (available on Apple Store and Google Play), users can wirelessly monitor measurements in real time. Standard accessories include test leads, a carrying bag, power adaptor, and English manual, all packaged in a compact gift box. At 384 g and measuring 206 mm × 95 mm × 55 mm, the UT171C balances portability with rugged performance for field and bench applications alike.
