World's Premier Digital Multimeter. Superior Accuracy and High Response, Topped with Safety Terminal Shutters

The Hioki DT4200 Digital Multimeter Series consist of a complete lineup of 9 models ranging from professional to industrial to pocket meters. The DT4281 is our top-of-the-line high-precision 60000 count digital multimeter with all of the functions and features required for advanced testing in complex power and electrical applications.

Key Features

60000 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)

Measures large currents with optional clamp probe (only for DT4281, which has no 10 A terminal for accident prevention)

Terminal shutter mechanism (prevents erroneous test lead insertion)

Dual display lets you check voltage and frequency simultaneously

The ultimate digital multimeter, featuring a design focused on safety that’s critical for electrical work

The DT4281, which is part of Hioki’s DT4280 series of high-end digital multimeters, is designed for maximum safety in electrical work. Connect an AC clamp to safely measure current.

- DC current measurement?600.00μA / 6000.0μA / 60.000mA / 600.00mA

- AC current measurement?600.00μA / 6000.0μA / 60.000mA / 600.00mA

- Directly connect an AC clamp sensor

Accurately measure the voltage output from the secondary sides of inverters by eliminating harmonic components

Measure the fundamental wave alone by eliminating harmonic components with the DT4281’s low-pass filter function.

Measure the ripple voltage of DC charging systems

Measure ripple voltage with a superposed DC signal by using peak value measurement and DC + AC voltage measurement.

Percentage display for 4 to 20 mA instrumentation signals

The digital multimeter can convert and display instrumentation signals of 4 to 20 mA or 0 to 20 mA representing properties such as temperature, pressure, and flow rate from a transducer or other device that converts sensor data into an electrical signal.

600.00 μA range for measuring very low currents used by gas-burning devices

Accurately measure the very low currents such as burner flame currents.

Clamp-on sensor based current measurement eliminates the cause of accidents

Mistakenly measuring voltage using the current range may lead to a short-circuit. The DT4281 eliminates the root cause of such accidents by providing clamp-on sensor based current measurement functionality instead of using conventional probes.

True RMS measurement for accurate measurement of even distorted current waveforms

Digital multimeters implement two types of measurement: mean-value measurement and true RMS measurement. The two methods yield significantly different measurement results for current waveforms, which are often distorted. For accurate measurement, it is necessary to use an instrument with true RMS capability.
