PTS can offer colour measurements (change in colour, yellowness/whiteness indices and grayscale) using the Ultrascan Pro from Hunterlab.
The D65 illumination source is calibrated prior to measurements using the standards Box with the white, green and black tiles.
The Ultrascan Pro has an extended wavelength range into the near infrared and near ultraviolet that permits the measurements of camouflage materials and UV blockers.
Whatever your requirements can measure from opaque solids, clear liquids and transparent films.
The unit can measure both reflected and transmitted colour, spectral reflectance, spectral transmittance and transmission haze.
Whether you have defined whiteness or yellowness indices for your material or simply want to determine the degree that your material shifts away from ideal white, we can offer you the service with our Ultrascan Pro.
