Customizing values

Gloss testers from different manufacturers often have slight differences in linearity. L&W Gloss Tester therefore has built-in functions for adjusting the linearity to comply with other instruments. The zero reference point and amplification can be set so that the measurement results agree with those of an existing instrument.

Adjustable start functions

The measurement begins automatically when a sample is placed in the measuring gap. Alternatively, the measurement can be started with a foot switch or by pressing a button.

Inspection opening for sample adjustments

The sample is lifted against the measurement aperture by a measuring plate. This plate has a suction ring that holds the sample flat. The suction plate is moveable so that it is always in the same position relative to the measurement system. This guarantees good repeatability of measurements. Each measurement takes approximately four seconds.

The sample’s position can be assessed easily via the inspection hatch. If required, the position can be accurately adjusted. In that way, selected spots on the sample can be measured precisely.
The halogen lamp in L&W Gloss Tester has a long life, and only needs to be changed about every six months. Changing the lamp is simple as the measurement system can be loosened and removed. Specific accessories make fitting of the new lamp easy.
