Hioki DT4221 Digital Multimeter Pocket Model

Hioki DT4221 – Digital Multi Meter Standard Model

The DT4221 is a pocket-sized digital multimeter designed specifically for electrical work requiring optimal safety, with ±0.5% DC V accuracy and wide 40Hz to 1kHz AC V bandwidth.

The Hioki DT4200 Digital Multimeter Series consist of a complete lineup of 9 models ranging from professional to industrial to pocket meters, delivering a super fast response rate and safety features that take electrical testing to a higher level.
 

Field-Proven Strength and Usability DT4200 series

Robust design capable of withstanding a drop from a height of 1 m onto concrete

To test our products’ ability to withstand mechanical shock, we repeatedly drop them from a height of at least 1 m until they break. This drop-testing regime leads to more robust products by fostering a series of design improvements.

Preventing instrument failure by keeping out dust

If dust gets into the instrument’s enclosure, it can cause the device to fail. Since dust can get into the instrument especially easily through the gap around the rotary switch, the DT4200 series incorporates a dustproof part known as an O-ring where the rotary switch is mounted to improve the device’s dust resistance.

Fast, accurate measurement of the output voltage on the secondary side of an inverter

The DT series can accurately measure the voltage on the secondary side of an inverter, just like a power meter. Its low-pass filter rejects harmonic components so that the fundamental wave can be isolated and accurately measured.

True RMS measurement for accurate measurement of even distorted current waveforms

Current waveforms are often distorted, causing the average-value and true RMS measurement methods to yield different results. To obtain accurate readings, RMS measurement is indispensable.

Outstanding viewing angle so display is easy to read at an angle or even in a dim location

The DT4200 series features a display with a wide viewing angle and a backlight function so that it’s easy to read, even when you can’t view the screen from the front or when making measurements in a dim location.

Rotary switch that’s easy to operate even when wearing gloves

The DT4200’s rotary switch is designed to be easy to turn even when wearing thick work gloves, for example while working in hazardous measurement locations or harsh conditions.

Outstanding hands-free ease of use in the field when working with numerous measurement locations

It’s hard to carry out work tasks smoothly when you’re juggling a measuring instrument, probes, recording paper, and other supplies. Field concerns like these are resolved by the DT4200’s magnetic strap, auto-hold function, and ability to save results in its internal memory. These capabilities boost work efficiency and help reduce work times.

*The auto-hold function is available exclusively in high-end and standard models. The ability to save results in internal memory is available exclusively in high-end models.

Extensive selection of probe tips that you can choose based on the measurement location, improving ease of measurement

With the DT4200, you can choose the probe type that best suits your measurement location, making it possible to measure in areas that can’t be reached with conventional probes and busbars that you wish to clamp between probes.

*Compatible probe tips vary with the DMM model. Please see page 16. The optional Connection Cable L4930 is required in order to use the probes shown at the left.
