The UT197PV is the solar build of UNI-T's rugged True-RMS multimeter: rated CAT IV 1000 V / CAT III 1500 V, sealed to IP67, and rated for a 5 m drop, with voltage ranges raised to 2500 V DC and 1500 V AC for photovoltaic strings and combiners. It also measures power directly — active, apparent, and reactive, with power factor — so you can read load behaviour, not just volts and amps.
True-RMS sensing, a low-impedance mode, VFC/VFD mode, loop read, and a Bluetooth app cover the rest of the field set, with AC/DC current to 1000 A and combined AC+DC measurement. It's backed by UNI-T's nearly 40 years of test-meter manufacturing.

UT197PV Details
PV Voltage Headroom
Raised ranges of 2500 V DC and 1500 V AC keep photovoltaic string and combiner measurements on-scale and within the meter's CAT IV 1000 V / CAT III 1500 V rating, where a standard 1000 V meter falls short.
Direct Power Measurement
Beyond volts and amps, the UT197PV reads active, apparent, and reactive power with power factor — useful for understanding inverter and load behaviour on a PV or industrial circuit without a separate power meter.
Built to Take Abuse
IP67 sealing and a 5 m drop rating handle rooftops and harsh outdoor sites, and True-RMS sensing keeps AC accurate on the distorted waveforms around inverters.
Field Tools & Connectivity
A low-impedance mode rejects ghost voltages, a VFC/VFD mode and loop read cover drive and process work, and a Bluetooth app captures readings to a phone.
