Aquimid principle experimenter is a measure of buoyancy, and the experiment device proves that the gravity of a liquid immersed in a liquid is equal to the gravity of a liquid diskharged by an object, known as aquimid principle

Advantages: this set of instruments is developed and produced by xuzhou gold key company according to the national education commission standard. it uses large volume floating mass (white cylinder) to diskharge more water and the experimental results are more obvious.

Iii. experimental uses: 1. verification of volume measurement by drainage method

-measurement of buoyancy by experimental method

-experiment to verify archimedes' principle.

Set one: 2n demonstration of the force meter plus archimedes principle experimenter

Set two: 5n demonstration force meter plus archimedes principle experimenter

Set three: 2n plus 5n demo hygrometer one each

Set of four: 2n demonstration force meter

Set of five: 5n demonstration force meter

Demonstration of the force meter

I. purpose:

The instrument is used to demonstrate the size of the measuring force and the weight of the said object, and the relationship between the length of spring elongation and the tension can be studied in teaching.

Ii. structure:

This instrument is composed of spring, lifting ring adjustment pointer, scale plate, hook and so on.

Iii. methods of use:

When used, the demometer pointer is adjusted to 0 scale, the upper lifting ring is pulled to the vertical direction and the object is hung on the hook. the final scale of the pointer is the size of the force (weight) of the object being measured.

Iv. points to note:

-do not exceed the scale limit.

-scale panel do not contact corrosive or sharp ob
