UNI-T UT171B Industrial True-RMS Multimeter

Overview

Rated CAT III 1000 V / CAT IV 600 V, the UT171B is a 60,000-count True-RMS multimeter built for plant and process work. The high count resolves small changes other meters round off, True-RMS keeps AC readings accurate on the distorted waveforms around drives and switching loads, and a high-contrast EBTN display stays readable on a plant floor.

It covers DC voltage to Β±(0.025%+5), AC and DC current to 10 A, resistance, capacitance, frequency to 10 MHz, and temperature to 1000 ℃, with non-contact voltage detection and storage for 9999 readings. A 7.4 V rechargeable Li-ion pack and 1 m drop rating suit daily field use. It's backed by UNI-T's nearly 40 years of test-meter manufacturing.

UT171B Details

60,000-Count True-RMS Measurement

The 60,000-count display resolves fine detail across the range, and True-RMS sensing keeps AC voltage and current accurate on the non-sinusoidal waveforms common around variable-frequency drives and electronic loads β€” where average-responding meters read low.

Industrial Accuracy & Bandwidth

DC voltage accuracy of Β±(0.025%+5) and 100 kHz AC bandwidth cover precise troubleshooting and signal work, with resistance to 60 MΞ©, capacitance to 60 mF, frequency to 10 MHz, and thermocouple temperature to 1000 ℃.

Safe Measurement Features

Non-contact voltage detection flags live conductors before you probe, and a low-impedance ACV mode loads out induced ghost voltages so a de-energized circuit reads as dead. The CAT III 1000 V / CAT IV 600 V rating covers distribution-level work.

Field Build

An EBTN display holds contrast at wide angles and in bright light, a 7.4 V 2000 mAh rechargeable pack runs long shifts, and a 1 m drop rating handles the knocks of plant use.

Applications

Plant and process troubleshooting; motor-drive and control-panel work where True-RMS and LoZ matter; commissioning and preventive maintenance; and bench or field measurement that needs 60,000-count resolution.

Frequently Asked Questions

What does 60,000-count resolution give me?

Finer reading detail than a typical 6,000-count meter β€” small changes that would otherwise be rounded off stay visible.

Is the UT171B True-RMS?

Yes β€” AC voltage and current are True-RMS, accurate on distorted waveforms around drives and electronic loads.

How does the UT171B differ from the UT171C?

The UT171B uses an EBTN display and includes NCV; the UT171C uses an OLED display and adds a square-wave output. Core measurement performance is the same.
