Presto manufactures Box Compression Tester to measure the stacking potential and compression strength of paper tanks, cartons, paper cases, beehive crates, etc. It is designed mainly to measure the compression strength of the corrugated boxes and the range of pressure and weight which is required to crush the cardboard completely in a given period of time to measure its maximum stacking potential.
Box compression tester is a test machine with a solid base which has user-friendly controls. The cardboards must have sufficient compression strength so that they do not get crushed when stacked one above the other at the time of storage. The compression strength of a box can be calculated by placing a carton on a platform and by pushing the concurrent plate towards the specimen to rupture the specimen completely. The instrument comprises of a digital indicator to measure the strength of the box digitally.
