UNI-T UT281F clamp meter
Details
The UNI-T UT281F is a True-RMS flexible clamp meter with single-phase power analysis, built for high-current work in industrial and utility environments. The meter can measure up to 10000A AC current with a high sensitivity down to 100mA, and has a coil length of 110cm that fits around conductors up to 350mm in diameter.
Besides current and voltage, the UT281F measures active power (kW), apparent power (kVA), reactive power (kVAR), accumulated energy (kWh), power factor and phase angle. It also measures frequency from 10Hz to 30kHz. The UT281F has a 6000 count LCD display and can send measurements over Bluetooth 5.0 to the UNI-T Smart Measure app for data logging and exporting. Other functions of the clamp meter are 1000A inrush current capture, AC/DC voltage auto identification, internal data storage for 1050 sets, data hold, auto power off and a backlight in the display.
