Four-point rubber contact adaptor - small aperture

The four‑point rubber contact adaptor is designed for measuring cylindrical and regularly curved objects such as pipes, tubes and rods. With the 2 mm gloss spot size provided by the small‑area optics, the device is suitable for measuring the gloss of cylinders with diameters down to 40 mm, while still maintaining reliable alignment on the curvature.
​

Its four certified rubber contact points support the instrument along the long axis of the object, positioning the gloss aperture precisely on the curved surface for stable, repeatable readings. The rubber material is compatible with paint shop environments and minimises the risk of marking fresh or sensitive coatings during measurement.

For best results when measuring cylinders place the instrument along the flattest edge of the sample as shown below.
