PMLQ-500 sponge foam falling ball rebound coefficient tester Introduction: The slow rebound tester is suitable for measuring the falling ball rebound performance of soft polyurethane foam. The falling ball rebound instrument freely falls on the foam plastic sample at the specified height through a steel ball with the diameter and mass specified in the standard, and automatically calculates the percentage (i.e. rebound rate) of the ratio of the height of the steel ball rebound to the height of the steel ball drop, which represents the rebound performance of the foam plastic. According to the standard testing requirements, each group consists of 3 samples, and each sample is tested three times. The normal value is taken each time, and the average of the three normal values is taken to calculate the rebound height and rebound rate. This instrument meets the standard requirements, automatically records data and judges the normal value, automatically calculates the average rebound height and average rebound rate, and can also set numbers and save data for different batches of samples for easy query and management. It can also print the current test data. Technical parameters: Steel ball drop height: 460mm (national standard)/500mm (American standard) Steel ball diameter: ￠ 16mm Highly transparent organic glass conduit, inner diameter: ￠ 50MM Precision of ball rebound rate:<1% Sample size: 100 mm × 100 mm × 100 (50) mm Sample quantity: 3 sets Height recognition: Automatically recognize height and save it Rebound rate calculation: Single rebound rate and automatically calculate the average value Reading: with scale indication, supports manual reading Steel ball release: automatic release, manual release Placement method: desktop, suitable for placement on the desktop Host dimensions: -560 * 360 * 860 (mm) Supply voltage: 220V/50HZ Equipment weight: 25KG
