Introduction:
It is mainly used to test whether the quality of the Rockwell clamp meets the requirements, and also to measure the increase in the distance between the two pointers of the Rockwell clamp after filling the Rockwell ring mold with cement slurry of standard consistency, curing and boiling for a certain period of time to determine the stability of the cement. It is mainly used to test whether the quality of the clamp meets the requirements, and also to measure the increase in the distance between the two pointers of the clamp before and after boiling to determine the stability of the cement. The product meets the requirements of GB/T1346 and ISO9597 standards. The LD-50 cement Rockwell clamp tester consists of components such as a bracket, ruler, and base.

Parameters:
Special weight: 300g.
△ value scale plate small engraving distance: 0.5MM.
Net weight: 1.65KG.

use:
The elasticity requirement test of the Rayleigh clamp requires fixing the string on the measuring instrument to the root of one pointer of the Rayleigh clamp, hanging a 300g weight on the root of the other pointer, and reading on the left ruler.
△ Expansion value measurement: Place the Le Chatelier clamp with the test piece taken out of the boiling box on the cushion block, with the pointer facing up. After leveling, read the upper ruler. Then calculate the expansion value according to GB1346-89.

Maintenance:
Regularly check the verticality of the left arm bracket and the support rod, and whether all fasteners are loose.
There should be no rust, stains, dirt or other substances on the cushion block.
After use, apply anti rust oil to the ruler and store it properly to avoid rust and damage.
