Today, colorimeters, spectrophotometers and spectrophotometric colorimeters (sometimes referred to as spectrocolorimeters) are the most commonly used instruments for measuring colour worldwide.

One of the most commonly used spectrophotometers in industry is the Sphere Geometry (d/8 or 8/d), Reflectance, Spectrophotometer.

The TR 500 & TR 520 are cost effective, versatile, handheld, sphere, spectrophotometers that are designed to give fast, precise and accurate colour measurement information on a range of products.

With one critical caveat: for precise colour measurement the sample needs to be in direct contact with the instrument's measuring port.

No ambient light from the local environment should interfere with the instrument's measurement.

This is where the TR Accessory comes into its own.
