HIOKI DT4281 | High-Precision Digital Multimeter | 60,000 Counts, ±0.025% DCV
The HIOKI DT4281 is a high-precision DT4200-series multimeter with a 5-digit, 60,000-count display and DC voltage accuracy of ±0.025%. It suits R&D, power electronics and calibration work; current is measured through an optional clamp probe rather than a 10 A terminal.
- AC voltage frequency response 20 Hz to 100 kHz
- Low-pass filter for inverter-driven waveforms
- Terminal shutter helps prevent wrong lead insertion
- Operating temperature -15 °C to 55 °C
- Optional USB communication for PC logging
