BC160 cement sand ratio meter

Mainly used to determine the dry shrinkage rate of mortar specimens at different ages and the expansion rate of expansive cement at different ages.

Instrument structure:

Composed of a base, standard rod, and measuring V-shaped frame, the measuring frame is equipped with a dial gauge.

Main specifications:

1. Standard pole length: L=158 ± 0.02mm
2. Two stroke micrometer: 0-1mm
3. Measurement accuracy: 0.001mm
4. Dimensions: 400x250x150mm
5. Weight: 1 kilogram

Instructions for use

1. Place the length gauge on a flat workbench, insert the dial gauge into the circular hole of the upper bracket, and place the standard rod on the V-shaped bracket (note: one side of the standard rod is marked, facing upwards, and always use this position to reduce measurement errors). Adjust the position of the dial gauge to about 50% of the full range, and then press the reset button to reset the value to zero.

2. Take the test piece out of the curing box, wipe off the surface moisture with deer skin cloth, gently place the test piece on the V-shaped bracket (note: generally, the end of the test piece with a label is facing upwards and outwards, or you can mark the label point yourself. To reduce errors, place the test piece in the same position during each measurement), and observe the reading of the dial gauge.
Example: If the reading on the table is 0.130mm, it should be read as 158.130mm or -0.260mm, and it should be read as 157.740mm (based on the standard rod length of 158mm plus or minus the corresponding value)

3. The length gauge is a precision measuring instrument, so it must be handled gently, kept clean, not collided, and not disassembled at will during use to avoid affecting measurement accuracy.
After use, it should be wiped clean and stored in the box for future use.
