View our latest version of this instrument, the CM-3600A

The CM-3220d benchtop spectrophotometer is a rugged, lightweight, and easy-to-use color measurement instrument. It is economical and suitable for both Point of Sale (POS) and Laboratory Quality Control applications.

Weighing approximately 4kg, the CM-3220d includes Numerical Gloss Control (NGC). This enables concurrent measurement with specular components included (SCI) and excluded (SCE). Xenon flash illumination technology, as well as inter-instrument agreement levels have not existed within instruments of this calibur and price point before now.

The affordable CM-3220d is operated using a PC with external software. The white calibration tile is fixed to the instrument, which allows for easy and reliable calibration. The instrument can also be flipped around and locked-in at a 90 degree angle to measure bigger samples.


  • Easy-to-use operated using a PC; only button found on instrument is on/off button
  • Lightweight and rugged weighs only about 4 kg, makes it ideal for either laboratory or Point-of-sale applications
  • Highly accurate and repeatable includes Xenon flash technology, SCI, SCE, and Numerical Gloss Control
  • Fixed calibration tile allows trouble free calibration
  • Measure any size sample the instrument can be flipped and locked at 90 degrees in order to measure smaller samples
