An optional horizontal axis lets impact energy be measured at more than one point on a specimen, rather than only at a single fixed location.

It is used where damage tolerance varies across a part, for example on a panel with ribs or joints, and a single central impact would not represent the component.

An anti-reflection system is available alongside it to keep optical sensing stable where surfaces would otherwise scatter the signal. Send the part drawing and we will confirm the axis travel you need: contact us.
