IEC AIR TRACK SPARK PAPER ROLL BLACK 10mx20mm
A spare roll of special black spark paper 20mm wide x 10m long used on IEC Air Tracks for spark recording.

It is placed under the white paper to leave a black dot on the underside of the white paper. As a spark passes through both papers to earth, a black dot is made on the underside of the white paper, thus forming a set of black dots that relate to velocity.

Can be used for many runs before it becomes exhausted.

NOTE: This is a genuine IEC product.
We believe in supporting Australian industry and only sell genuine IEC products, we do NOT sell imported clones of IEC products.
