The UT171C is the OLED version of UNI-T's 60,000-count industrial True-RMS multimeter, rated CAT III 1000 V / CAT IV 600 V. The OLED display gives deep contrast and a wide viewing angle in any light, and the meter adds a square-wave output for testing and calibration alongside the full industrial measurement set.

Measurement matches the rest of the series: DC voltage to ±(0.025%+5), AC and DC current to 10 A, resistance to 60 MΩ, capacitance to 60 mF, frequency to 10 MHz, and temperature to 1000 ℃, with True-RMS, a low-impedance ACV mode, and 9999-reading storage. A rechargeable Li-ion pack and 1 m drop rating keep it field-ready. It's backed by UNI-T's nearly 40 years of test-meter manufacturing.

UT171C Details

OLED Display

The OLED screen delivers deep contrast and a wide viewing angle that stays legible in bright sun and dim equipment rooms alike — a step up in readability for fast plant-floor work.

60,000-Count True-RMS Measurement

The 60,000-count display resolves fine detail, and True-RMS sensing keeps AC accurate on the distorted waveforms around drives and electronic loads where average-responding meters read low.

Square-Wave Output

A built-in square-wave output supports quick functional checks and calibration tasks in the field without a separate signal source.

Safe Measurement & Field Build

A low-impedance ACV mode loads out induced ghost voltages so a dead circuit reads dead, the CAT III 1000 V / CAT IV 600 V rating covers distribution work, and a rechargeable Li-ion pack with a 1 m drop rating handles daily use.

Applications

Plant and process troubleshooting; drive and control-panel work; commissioning and preventive maintenance; and any task where an OLED display and a square-wave output add value to a 60,000-count industrial meter.
