Detailed Product Overview


The Hioki DT4255 is a carefully designed True RMS digital multimeter built to meet the demands of modern electrical diagnostics and maintenance. It offers reliable measurement performance paired with thoughtfully engineered safety features, making it an excellent choice for both industrial settings and technical education.

The instrument is well-suited for analyzing inverter-driven systems. Its integrated low-pass filter ensures stable readings even when high-frequency harmonics are present. The dual display with bargraph enables simultaneous monitoring of voltage and frequency, making it suitable for evaluating variable speed drives and power quality parameters.

It is designed to protect the user from injury and the instrument from damage. Reliable input protection prevents damage caused by incorrect operation or short circuits. Additionally, the built-in non-contact voltage detection function enables users to identify live conductors without making direct contact. This function is particularly helpful during initial inspections, as it helps detect potentially dangerous voltages at an early stage and prevent accidents, especially in complex or high-risk environments.

The DT4255 supports precise True RMS measurement and provides reliable readings even for distorted AC voltage and current signals. This is particularly important in environments with frequency inverters or switching power supplies, where the signal deviates significantly from a sine wave. For current measurements, the instrument can be used with Hioki clamp-on sensors, which connect via a dedicated terminal and allow contactless operation without breaking the circuit.

Its broad operating range and durable housing make it suitable for challenging field conditions, while its intuitive design supports both experienced professionals and trainees in vocational education.

9010-50
9010-50 - AC Multi-Range Current Clamp, 500 A, 1 kHz, BNC Output
The 9010-50 is an AC multi-range current clamp with voltage output for measuring alternating currents from 10 A to 500 A AC. It provides 6 selectable ranges with a full scale output level of 0.2 V AC. The output sensitivity varies according to the selected range. The clamp features a frequency bandwidth of 1 kHz and is rated for measurement environments up to CAT III 600 V. It operates without an external power supply. The compact jaw design is intended for standard insulated conductors in electrical installations and industrial equipment. The measured signal is available via a BNC output connector with a fixed 3 m cable. The 9010-50 can be connected to digital multimeters, data acquisition systems, recorders or other measuring instruments with a compatible AC voltage input. When used with HIOKI digital multimeters that support clamp input, connection is made via the optional 9704 BNC adapter. The appropriate clamp range can be selected on the multimeter, allowing the measured value to be displayed directly in amperes. When used with other instruments, the voltage range should match the 0.2 V AC full scale output and the input impedance should be sufficiently high to maintain specified measurement performance.
