Yellow index meter

HunterLab AgeraYellow index meterBringing the color measurement of plastic particles to a new and different level of technology, it is easier to operate, more automated, and has more functions compared to any other product on the market today.

The 0 °/45 ° optical geometry structure combined with a measurement aperture of 45-52mm provides an angle that is in line with the human eye for "seeing" colors,Measure the yellowness index YI D1925, YI E313 (C/2, D65/10), Lab color value, L * a * b * color value, △ E and △ E * color difference of samples such as particles, slices, sheets, powders, etc., suitable for almost all applications of yellow index or whiteness index in plastic particles and plastic industry.

HunterLab AgeraYellow index meterKey Features:

1. 0 ° illumination/45 ° detection - measures and considers changes in texture and finishing effects; The way of "seeing" colors is consistent with human eye observation.

2. 51mm/30mm reflective hole - a wider range of sample size and structural changes for better observation of the sample. Meets the requirements of ASTM D6290 and HG/T3862 standards.

3. Full spectrum LED -5-year lifespan design, no need for replacement, analog D65 is excellent.

4. Automatic reference calibration - built-in standard board ensures testing stability.

5. Dual light path——Accuracy, stability, and durability.

6. Touch screen - built-in Android system, one click calibration, one click measurement

7. There are two types of testing directions: hole facing up or hole facing forward - for testing liquids, solids, powders, or slurries, with optional brackets that can also be hole facing down.

8. Fluorescence measurement.

9. Built in 60 ° gloss testing function, compliant with ASTM D523 standard

10. *The automatic particle testing device automatically completes multiple measurements of the average value after adding the sample at once, obtaining more stable YI yellowing index values and other required chromaticity index values.
