Colour meters
Here you will find colour meters for both colour and luminance for measuring surface colours of products.  Our professional colour meters include the CR series. With these colour meters you can read the difference in colour in L d*a*b*, L*C*H* and Delta E*ab according to your requirements. The most popular model of colour meter in our range of products is the PCE-RGB. Aside from being easy to use and economical, our colour meters are used for determining the location of a colour on the XYZ axis of non-radioactive products. The geometry of the measurement of these colours, with luminosity including a field of measurement of 8mm allow for universal use for all types of materials. If you prefer devices with an external sensor, you can be confident in choosing the CTA device. The range of applications of colour meters is extensive and includes industry, agriculture, crafts, commerce, as well as reasearch and development. urthermore, these devices are used by artisans, paint manufacturers, architects, painters and designers for testing colours (for colour card, NCS, RAL, HKS) or for establishing colours after mixing various colours. We can also make ISO 9000 calibration certificates for colour meters or factory calibration documents. If you don't find the vibration meters you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: +44 ( 0 ) 191 377 3398 and our technical staff will advise you regarding our measuring instruments.

Information about the measurement of colour: Different colour spaces are classified by a coordinating system n which different clours are shown by coordinates on an axis. Conditioned by the structure of the human eye and taking into account that the one observing the colour will be human, these colours are placed on three axis. They are used in some 30 systems of colour space. The images above show the most important colour spaces. A fundamental problem od adjusting colours, in developing colour meters, is the sensitivity of the human eye. The problem is that the colour spaces don't coincide with the perception of the human eye. When colours are mixed, problems exsist in the perception of the area for the colour yellow. On the other hand, wth a mix of colour dominated by the colour blue, you can simulate a lighter shade of colour to the human eye. To eliminate  such problems, they are used with a colour meter frequency, such as the fabrication of different shades. The manufacturer of a product, sends a product out to be painted or treated having an agreement on using an established colour standard (such as RGB colour space). Both possess the same colour meter. The factory, follows the agreement, verifies the test output of the colour of the product and ships it as it meets the standard. They then continue with treating the product then check it against the frequency of its colur when it arrived. In cases where the result is contrary to the agreement, the two departments can communicate exactly about the difference in colours and use the same colour space in corresponding tests.
