UNI-T UT171C Industrial True RMS Digital Multimeter

UNI-T UT171C Industrial True RMS Digital Multimeter

The UNI-T UT171C is a robust, industrial-grade True RMS digital multimeter built for demanding professional environments. It features a high-resolution display (≈ 60,000 counts) and supports measurements up to 1000 V AC/DC and 10 A AC/DC, making it suitable for heavy electrical, automation and control system work.

Key standout features include:

• True RMS measurement to ensure accuracy with non-sinusoidal waveforms.

• OLED display with very good readout even under low temperature conditions (down to around -30 °C) and a 31-segment analog bar-graph for trend visualization.

• A full suite of functions: AC/DC voltage & current, resistance up to 60 MΩ, capacitance, frequency (10 Hz to 10 MHz), temperature (-40 °C to 1000 °C), duty cycle, diode/continuity test, 4-20 mA loop function and LoZ (low impedance) ACV to handle ghost voltages.

• Connectivity & logging: USB/Bluetooth interface support for data transfer, data logging up to ~9,999 records, and built-in square-wave output for industrial signal diagnostics.

• Safety and ruggedness: Rated for CAT III 1000 V / CAT IV 600 V, making it viable for industrial power systems.

• Rechargeable Li-ion power supply (7.4 V ~2000 mAh) with auto power off, mis-plug alarm, NCV detection, relative mode, MIN/MAX/PEAK hold.

Summary: If you need a multimeter that goes beyond simple bench or hobby use, into the realm of industrial automation, control panels, heavy-duty power distribution, PLC/SCADA systems, and environmental extremes, the UT171C delivers strong value. The advanced feature set makes it particularly suitable for maintenance engineers, instrumentation specialists, automation technicians and field service professionals.
