UNI-T UT281F 10000A Flex Clamp Clamp Meter adalah alat ukur listrik profesional jenis flexible clamp meter yang dirancang untuk pengukuran arus AC besar pada instalasi industri, panel distribusi, busbar, dan sistem tenaga listrik tanpa perlu memutus kabel. Alat ini menggunakan flexible Rogowski coil sepanjang 1,1 meter sehingga mudah digunakan pada area sempit atau kabel berdiameter besar yang sulit dijangkau clamp meter biasa.
UT281F mendukung pengukuran arus hingga 10.000A True RMS dengan akurasi tinggi, sehingga cocok digunakan pada sistem kelistrikan industri, pembangkit listrik, manufaktur, smelter, hingga photovoltaic station. Selain pengukuran arus, alat ini juga mampu mengukur tegangan AC/DC hingga 1000V, resistansi, frekuensi, inrush current, serta analisis daya seperti kW, kVA, kVAR, power factor, phase angle, dan energi kWh.
