Hioki DM7275 Precision DC Voltmeter memberikan akurasi pengukuran unggul 20 ppm (0,002%), tingkat akurasi yang dituntut oleh aplikasi canggih seperti uji penuaan baterai lithium-ion. Fitur utama lainnya termasuk pemeriksaan kontak untuk memaksimalkan keandalan pengukuran, kompensasi binning dan suhu, membuat voltmeter ideal untuk pengembangan dan pembuatan baterai Li-ion, kapasitor lapisan ganda listrik, komponen kendaraan listrik, dan perangkat generasi berikutnya.
