Caliper gauges, micrometers and spherometers are used for the accurate measurement of lengths, thicknesses, diameters and curvatures. A mechanical balance is used for weight determinations, a decade counter is used for accurate time measurements. Measuring procedures, accuracy of measurement and reading accuracy are demonstrated.

Tasks :

Determination of the volume of tubes with the caliper gauge.

Determination of the thickness of wires, cubes and plates with the micrometer.

Determination of the thickness of plates and the radius of curvature of watch glasses with the spherometer.
