The melting point meter is used to measure the melting point of the sample;

The colorimeter is used to measure the tristimulus value or the chromaticity coordinate of the object color;

Polarimeter can measure the concentration, content and purity of the substance by measuring the optical rotation of the sample.

Refractometer is an instrument that uses light to test the concentration of a liquid.

Viscometer is a physical property analyzer that measures the viscosity of a fluid.

Whiteness meter is mainly suitable for measuring the whiteness of objects or powders with a non-colored surface, and the opacity of the paper can be accurately measured.
