16 New Current Sensor Models for Use with the Power Analyzer PW8001: 14 New Models, Order and Shipment Begin of All 16

Today (Dec. 17th 2021), HIOKI will begin order and shipment of 16 new current sensors designed to achieve high accuracy power measurements with the newly released Power Analyzer PW8001 (order and shipment on Dec. 24, 2021). In addition to the two new models announced September, we are proud to announce adding a surprising number of 14 new current sensors to the mix, with a sum total of 16 new models beginning order and shipment today.


1. Full Lineup

For highly accurate power measurement, current sensors must be handpicked for the device being measured. These new current sensors help create Hioki’s extensive lineup of current sensors that enable power measurements of a wide range of devices. In terms of amperage, the new sensors range from 50 to 2,000 A. In terms of frequency for the measurable current, the range is very wide at DC (0 Hz) to 10 MHz. Cable lengths can also be flexibly chosen for the situation at 3 or 10 meters without special ordering. 

2. Plug & Play

Since there are many factors that contribute to a current sensor accurately measuring currents, setting up is indispensable. Setting up your sensor has traditionally been a tiresome task, also linked to many a frustrating re-measurement caused by operational error. But these problems are now eradicated with the new sensors working in perfect harmony with the new Power Analyzer PW8001. Now, all you have to do for sensor settings is simply connect one of the new current sensors to the PW8001 and the power analyzer makes the main settings necessary for accurate measurement. With this new combination, measurement can be started immediately and mistakes avoided.

3. High Accuracy Measurement

This teamwork between the Power Analyzer and the 16 new current sensors also particularly contributes to highly accurate measurement. Among the data stored on the sensor (e.g. model and calibration data), calibration stands out in terms of its contribution to accuracy. This calibration data is automatically sent to the PW8001 and makes the power measurement much more accurate than ever before possible.
