Digital Edge Crush Tester for Corrugated Board

Edgewise compression tester that measures edge crush resistance (ECT) of corrugated board specimens, the main predictor of box stacking strength. Used in corrugated sheet plants and box makers.

Specification

A 25 x 100 mm board specimen stands on edge in a slotted holder and is compressed at 12.5 mm per minute until crushing. The peak force per unit length is the ECT value used in box compression calculations. The digital controller records peak load and reports kN/m.

Features

• Load cell 2 kN with peak hold
• Platen speed 12.5 +/- 2.5 mm/min
• Specimen holders for 25 mm and 32 mm heights
• Results in N/m and lb/in
• Self-calibrating load cell
