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.
