The R160 model is recommended when only an assessment of roundness, not straightness or cylindricity is needed. Whilst the R160 maintains a high level of measurement accuracy and performance reliability, it represents only a minimum of capital investment. 

In this model, the supporting column of the gauge is manually operated and allows workpieces of up to 500 mm in height to be measured. The stylus is a lever type, directionable by 180°; it is protected by bumps; the terminals are interchangeable in order to vary both the lengths and the diameter of the sphere of contact.

The cycle of measure guides the operator in the operations of table centering and levelling and subsequently in the acquisition of the profile. Besides the default cycles of measure it is also possible to make calculations on the previously acquired profiles; moreover it is possible to plan the cycle of acquisitions. This is very useful especially when you have to measure many similar workpieces, with the same parameters and you need to enhance the measuring speed.

The software allows you to choose the method of calculation to perform the measurement and to elaborate the results. For the Roundness: circumference of the minimum squares, circumference of minimum zone, minimum circumscribed circumference, maximum subscribed circumference. For the Flatness: plan of the minimum squares, plan of the minimum zone, minimum superior plan, maximum inferior plan. 

The tool can measure discontinuous surfaces, in fact it is also possible to evaluate the circular geometries even when the pick-up loses the contact with the surface; it is also possible to measure inside of caves thanks to the partial rotations of the table.

A large variety of accessories completes the SM Roundness testers equipment.
