SP-175 type mortar shrinkage and expansion meter wholesale price

Type mortar shrinkage expansion meter wholesale price
Operation and use:
Select the center height of the standard rod you need, and place the left end of the standard rod (as shown in the structural diagram) against the positioning column In the groove, the lower plane of the standard rod shelf is close to the reference surface of the base, and then slowly push the other end of the standard rod into the center of the instrument.
Loosen the set screw, and slowly insert the dial indicator into your In the selected adjustable column hole, make the dial indicator probe contact the right end of the standard rod, and then tighten the set screw to position the dial indicator on the instrument. Read and record the scale of the dial indicator at this time.
, The placement method of concrete specimens is the same.
The production, maintenance and shrinkage and expansion tests of concrete specimens are carried out in accordance with relevant standards such as B. Precautions for concrete shrinkage and expansion meters, concrete shrinkage and expansion meters should be placed on a flat surface On the workbench, the four feet should be evenly stressed. Do not focus on three points to prevent the instrument from deforming and affecting the accuracy.
The standard rod is the reference length unit of the instrument. It must be handled with care to prevent deformation.< br/>. The dial indicator is a precision component. The test piece should be placed and taken out gently and carefully, and do not collide with the meter frame and meter rod.
. After each use, a little lubrication should be applied to the surface of the non-painted parts. Oil, apply instrument oil on the surface of the dial indicator's moving parts.
In environments with high dust concentrations or long periods of outage, dust-proof measures should be taken.
