Hioki DT4281
1000V, Multi-function Digital Multimeter
DC+ACV, Temperature, Capacitance, and Frequency

  • 60,000 count, 5-digit display, high-resolution measurements
  • ±0.025% DC V basic accuracy, wide 20 Hz to 100 kHz AC V frequency characteristics
  • Low-pass filter cuts high harmonics (when measuring inverter fundamental waveforms)
  • Includes multiple measurement functions such as DC+ACV, temperature, capacitance, and frequency
  • Includes terminal shutter mechanism for accident prevention (prevents erroneous test lead insertion)
  • Measures large currents with optional clamp probe (only for DT4281, which has no 10 A terminal for accident prevention)
  • USB communications function supports PC measurements (optional)
  • Broad -15 (5°F) to 55°C (131°F) operating temperature range
