Increasingly, specifications and standards require an assessment of gloss. Gloss measurement is necessary to monitor the uniformity, compatibility, or possibly the deterioration of any protective gloss finish.

Using the 4 adjustable posts and the small measurement area, the Elcometer 400 is perhaps the only glossmeter designed specifically for measuring curved surfaces, small components and complex shapes.

Continuous reading mode allows the rapid assessment of finish variation. Measures a whole range of products and designs - including:

• Paint finish
• Wood varnish
• Automobile parts - trim, steering wheel, dashboard
• Plastics - window frames, drinks bottles
• Glazed ceramics
• Frosted glass ….. and much, much more

The Elcometer 400 Novo-Curve™ is a bench top instrument and parts to be measured are placed over the central aperture. A positioning system allows repeatable measurements. Statistical analysis is available at the touch of a button and results may be downloaded to a PC via USB interface.

The Elcometer 400 Novo-Curve™ measures over an area approximately 3% of the size of that utilised by a standard glossmeter.

This instrument is designed to store and average up to 199 readings, so it is possible to "average" a larger area and by using a suitable sample population, it is possible to obtain representative results by statistical analysis.

Cylinder Measurement Jig

The detachable Cylinder Measurement Jig gives improved repeatability for cylindrical objects from 5mm radius up to 100mm. Foam baffles exclude ambient light and hold the cylinder in optimum measurement position. The Jig is fully adjustable and can be used for cylinders from 5mm -100mm radius.

• Has been used for extruded plastic pipes, chromed metal work & designer writing pens.
• Achieves repeatability as low as 0.5 GU on curved surfaces.

Gloss Measurement

Gloss is an important aspect of coating fininsh. In order to allow comparison of measurement values an international standard was established. To identify a difference over the complete range from matt to high gloss, 3 geometries are used; 20°, 60° and 85° measured perpendicular to the surface being inspected.

In addition there are industry specific applications for 45° and 75° geometries which are indicated below
