Sirchie EFR300 90 cm Tri-Fold Scale

The Sirchie EFR300 is a 90 cm forensic measuring scale designed for crime scene documentation. It provides a rigid reference in photographs and suits investigators who need a portable, multi-configuration scale.

Check your kit bag and mounting needs

The scale folds to 30 x 30 cm or 30 x 60 cm, so confirm the folded size fits your evidence kit or vehicle compartment. A 1/4 inch hole allows hanging, but no hardware is included; verify you have a suitable hook or nail if wall mounting is required.

0.040 inch polystyrene with double-sided printing

The yellow polystyrene body is 0.040 inches thick and 3.17 cm wide, printed on both sides with black divisions for horizontal or vertical reading. Three modes — straight, right angle and dual right angle — let the same scale adapt to floor, wall or corner evidence without carrying multiple tools.

Questions about this item

What does the EFR300 package contain and is anything else needed to use it?

The box holds the 90 cm tri-fold scale printed on both sides with a 1/4" hanging hole. No extra items are required for basic measuring tasks.

Which length configuration should I select for a 60 cm wide evidence area?

Use the right-angle mode which gives a 30 cm by 60 cm L-shape, or open it fully for a straight 90 cm run.

How does the 0.040" thick polystyrene perform when the scale is folded into the dual right-angle shape?

The rigid 0.040" material keeps the 30 cm by 30 cm corner flat and stable on uneven surfaces without bending.
