ISO 9895 Paper Board Compressive Strength SCT Short Span Crush Tester Compressive Strength of Linerboard and Corrugated Paper
1. Introduction
RH-SCT short-distance compression tester can quickly measure the compressive strength of linerboard and corrugated paper. The compressive strength determines the stackability of corrugated boxes. The purpose of measuring the compressive strength is to help manufacturers use as little raw material as possible to produce cartons with high compressive strength.

4. Product Features
High-precision force sensor is used, and the accuracy is controlled at <0.5% when leaving the factory, which is better than the ±1% of ISO standard.
Precision ball screw transmission, aluminum alloy panel, high-quality stainless steel chuck and reasonable design ensure that the instrument is durable.
High-definition touch screen display and friendly human-machine interface operation. The test is completed fully automatically, with test data statistical processing function, micro printer output, and can also be connected to a computer for operation. When connected to a computer, in addition to automatically memorizing and storing results, the compression curve can also be displayed and saved.
High-performance stepper motor and American chip control are used to ensure that the instrument has accurate transmission and fast and efficient testing.
The instrument is specially set up with a calibration procedure to facilitate the measurement and calibration department (third party) to calibrate the instrument. The calibration weights are equipped at the factory, and users can easily calibrate the instrument themselves
