The DW22 Probe Weight is an optional accessory designed to improve the contact between the measurement probe and the test specimen during iron loss testing. By applying a consistent downward force, the probe weight helps maintain uniform contact across the sample surface, resulting in more stable, repeatable, and accurate measurements.

Manufactured in a compact cylindrical design, the probe weight is easy to position over both the DW22 Big Probe and DW22 Small Probe. It is especially useful when testing thin electrical steel sheets or samples with slight surface irregularities where maintaining consistent probe contact is critical.
