Description
Overview
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.

Frequently Asked Questions
What does the UT171C add over the UT171B?
An OLED display and a square-wave output. Measurement performance — 60,000 count, True-RMS, ranges, and accuracy — is the same.
Is the display readable outdoors?
Yes — the OLED screen holds contrast across viewing angles in bright and low light.
Is it True-RMS?
Yes, on both AC voltage and current.
