YL4520 spectrophotometer is a color measuring instrument with 45/0 optical geometry(45 ring-shaped illumination, vertical viewing), to achieve precise non-contact measurement between the measuring probe and the sample like liquids, sauces, powders, etc, which is developed by 3nh independently with independent intellectual property.

YL4520 non-contact benchtop spectrophotometer can be applied for accurate color analysis and transmission in laboratories and R & D industries; it can also be used for accurate color measurement and quality control of automated production lines; it is widely used in cosmetics, irregular metal, fruits and vegetables, food hygiene, plastic electronics, paint and ink, printing, ceramics and other industries. Its unique innovative design can not only provide non-contact measurement scheme directly from the production line, but also ensure stable and high-precision measurement results.

YL4520 non-contact spectrophotometer will not touch the sample in the measurement process, to prevent damage to the sample, but also to avoid cross contamination.

 

PRODUCT FEATURES

1. non-contact, 45 / 0 geometric optical structure to measure the reflectance and chromaticity of objects

2. The movable measuring head moves up and down according to the actual height of the measured object

3. Large touch screen measurement interface, real-time display of measurement data, to realize more measurement functions

4. Multiple measurement modes (sample, quality control, continuous statistical mode) can be selected to meet the personalized needs
