reflection polymer melt probe · find out how the equitech reflection polymer melt probe can...

THE CHALLENGE: COLOR MONITORING FOR POLYMER MELTSTo minimize color variation in manufacturedmaterials requires sensitivity and specificity. A probe must be able to quickly detectcolor values of reflected light withoutinterference from stray light.

THE SOLUTION: THEEQUITECH REFLECTIONPOLYMER MELT PROBEBuilt specifically for monitoring color in extrudedthermoplastics applications, this probe combinesillumination with detection to measure reflectedlight and precisely monitor color.

THE INNOVATION:• Seven illumination fibers are evenly spaced

around the probe circumference

• Illumination fibers are angled at 28 degrees from surface normal

• Reflected light is picked up by a single fiber at 0 degrees from normal
