Drop ball rebound tester has both the manual and automatic reading advantages - Database & Sql Blog Articles

The accuracy of the automatic degree is relatively high, but if the test result is wrong due to an operation error or due to unevenness of the sample, the comparison can be made by manual reading, which effectively reduces the probability of error, thereby making the test data more rigorous.

Scope and function:

Suitable for measuring the falling ball resilience of flexible polyurethane foam.

The instrument can freely fall on the sponge foam sample at a specified height by a steel ball of standard specified diameter and mass, and automatically calculate the percentage of the maximum height of the rebound of the steel ball and the ratio of the drop height of the steel ball (both rebound rate) to The rebound rate indicates the rebound resilience of the foam.

According to the standard test requirements, each sample has 3 samples, each sample is tested three times, each time taking the maximum value, and taking the average of the three maximum values ​​to obtain the rebound height and rebound rate. The instrument fully meets the standard requirements. Automatically record data and automatically determine the maximum value, automatically calculate the average rebound height and average rebound rate, and can set numbers and save data for different batches of samples, easy to query and manage, or print data on current test data. .

The instrument is controlled by German Siemens PLC, 7-inch touch screen Chinese operation, with convenient operation, reliable performance and high measurement accuracy. It is the most advanced sponge resilience test instrument in China.
