UNI-T UT197 Industrial True-RMS Multimeter
Overview
The UT197 is a True-RMS industrial multimeter rated CAT IV 1000 V and built to survive: sealed to IP67 and rated for a 5 m drop, it holds up where most handhelds don't. It measures AC/DC voltage and current to 1000 V and 10 A, combined AC+DC, resistance, capacitance, frequency, and temperature to 1000 ℃, and pairs to a Bluetooth app.
Working tools include a low-impedance (LoZ) mode, low-pass filter, VFC/VFD mode for drive outputs, a loop-read function, conductance, and duty cycle — the functions plant and field electricians reach for. It's backed by UNI-T's nearly 40 years of test-meter manufacturing.

UT197 Details
Built to Take Abuse
A CAT IV 1000 V rating, IP67 sealing, and a 5 m drop rating put the UT197 in a different durability class from typical handhelds — it keeps working after dust, water, and falls that would end other meters.
True-RMS & Drive Tools
True-RMS sensing keeps AC accurate on distorted waveforms, while a VFC/VFD mode and low-pass filter let you read the fundamental cleanly on variable-frequency-drive outputs.
Safe & Process-Ready Measurement
A low-impedance mode loads out induced ghost voltages so a dead circuit reads dead, and a loop-read function supports 4–20 mA process measurement alongside the standard electrical set.
Range & Connectivity
Combined AC+DC measurement, temperature to 1000 ℃, and a Bluetooth app cover a wide range of field tasks and let you capture readings to a phone.

Frequently Asked Questions
How rugged is the UT197?
It is rated CAT IV 1000 V, sealed to IP67, and rated for a 5 m drop — built for harsh field use.
Can it read variable-frequency drive outputs?
Yes — a VFC/VFD mode and a low-pass filter let you read the fundamental on a drive output.
How is the UT197 different from the UT197PV?
The UT197PV is the solar version: higher voltage ranges (2500 V DC / 1500 V AC) and built-in power measurement for PV work.
