Why measure gloss?
Gloss is an aspect of the visual perception of objects that is as important as colour when considering the psychological impact of products on a

A versatile solution for reflectometry measurement
The Novo-Shade Duo+ is a portable 45/0° reflectometer that can be used to assess either the shade of a surface (a simple indication of colour based on lightness/darkness) or calculate the opacity of a coating, plastic film or paper sample. By measuring using 45/0°, the Novo- Shade Duo+ measures the colour of a surface and not the specular reflectance (gloss).
Shade
Measure the shade of a surface on a greyscale
Opacity
Measure substrate opacity/hiding power
Cleanliness
Measure substrate cleanliness
Shade mode
To measure the shade of a coating simply place the instrument on the surface of the sample to be measured and press the centre button. The value is displayed on the screen. The shade measurement is based on a greyscale value where black has a value of zero and white is the value of the calibration standard included with the instrument.
Applications
Opacity mode
To measure the opacity of a coating, it must be drawn down on a Leneta-type opacity chart at the required film weight and allowed to fully dry. To measure the opacity of plastic film, paper, textile or any other semi-opaque material, the sample to be measured should be placed over a black and white test bed, a Leneta-type chart is also suggested.
Applications
Cleanliness mode
To measure cleanliness, clear tape is used to collect debris from the surface under test. This is then stuck to any suitable white substrate along with a sample of tape that is perfectly clean.
Measurements are made of the reference material and then of the tape, cleanliness is calculated automatically.
Applications
Features
The instrument is controlled by pressing the relevant touch sensitive buttons. Functionality is dependent on which operating mode the instrument is in.
Pass/Fail
The Pass/Fail setup screen is used to enable/disable on-screen pass/fail indication and set min/max tolerancing for easy identification and reporting of non-confomances.
Software-free Rapid Data Transfer
USB connection to a computer instantly recognises the device as a drive location which facilitates the quick transfer of files using Windows File Explorer or similar software.
Power
20,000+ readings per charge. The instrument is rechargeable via USB/PC or mains.

Answers to common questions about our instruments and measurements
What glossmeter do I need?
Identify the surface that you wish to measure. Is it a flat surface? If so, it can be measured with a traditonal glossmeter. Curved surfaces
What is RSpec?
RSpec is the peak reflectance measured over a very narrow angular band in the specular direction (+/-) 0.0991º. RSpec is very sensitive to any texture
