With your technical sales representative, examine the instrument options you discovered here. The questions still to be addressed include:

- What is the measurable area of the sample? The instrument purchased must have a port size appropriate to the desired measurement area of the sample and/or sample handling devices must be available that allow repeatable measurements.

- Will the instrument be used for formulation or quality control? In general, sphere instruments such as the ColorQuest XE, UltraScan VIS or UltraScan Pro will be used for formulation.

- Is a computer to be used for instrument control? The ColorFlex, ColorQuest OnLine, ColorQuest XE, ColorQuest XT, ColorTrend HT, D25s, LabScan XE, and MiniScan XE Plus may be purchased in configurations that don't require a personal computer.

- Is UV control of the light source required? The ColorQuest XE, LabScan XE, SpectraProbe XE, UltraScan VIS and UltraScan Pro have automated UV control options.

- Is the ability to measure reflectance with the specular component included required? Only the ColorQuest XE, UltraScan VIS and UltraScan Pro can switch between RSIN and RSEX measurements.

Your sales representative will guide you in making your final decision and purchasing the right instrument for you.

Note: New instruments are released by HunterLab frequently, so you may have even more options than are mentioned here!
