NOVO-SHADE 45/0 Reflectometer

Statistical NOVO-SHADE is an instrument for measuring whiteness. It can be used to determine such effects as:

• Hiding power -- paints, inks, coatings
• Shade -- paints, auto trims, furniture
• Fading: textiles, clothing, plastics, any pigmented system
• Chalking -- paints
• Efficiency of detergents -- washing powders, cleaning fuilds
• Cleanliness & oxidisation of metal surfaces such as (blasted steel)

Features

• Instant readings may be captured at the press of button
• Alternatively continuous reading allows rapid assessment of surface variation by sliding the instrument whilst holding the read button
• Automatic calculation of max., min., mean and coefficient of variation
• Memory storage oof up to 999 readings
• Down loading of data a PC or directly to on-line printer
• Windows software for analysis and permanent data storage supplied
• Durability and stability achieved through solid optical block arrangement
• Patented auto-stabilisatio circuitry

A non-statistical NOVO-SHADE instrument without memory, statistical functions or computer interface facilities is available if these features are not required.

Principles of operation
The test surface is illuminated from a 45¡Æ angle. The intensity of scattered light at the perpendicular (i.e. 0¡Æ) is measured.

Data is recorded on a grey scale where black is 0% and white is 100%. Only shading is measured, irrespective of colour, and is referred to as whiteness.

Hiding power determination according to ISO 2814 involves measuring whiteness of a known film of test material on both a black (<5%) and a white (>75%; <85%) substrate. The ratio of these two readings gives the hiding power measurement.
