Non-contact spectrophotometer YR05481

Manufacturer:ย Kalstein


YR05481 spectrophotometer is a color measuring instrument that adopts D/8 (diffuse illumination, 8ยฐ direction reception, SCI includes specular reflection light) standard. , powder and other non-contact precision color measurement. It can be used for accurate color analysis and transmission in laboratories and R&D industries; it can also be used for accurate color measurement and color quality control in automated production lines.

Instrument Features
  • Professional D/8 optical structure.
  • Non-contact, D/8 optical structure measures the reflectivity and chromaticity value of objects.
  • D/8 has wider applicability and supports color matching.
The measurement height is adjustable

The movable measuring head can be adjusted up and down according to the actual height of the measured object, and the measuring height can be stored, and the maximum support 160mm sample.

Simple to use and easy to operate

Simple operation interface, no need for complicated settings, non-professionals can also easily measure, touch-type large-screen measurement interface, real-time display of measurement data, more measurement functions are realized.ย 

Various measurement modes

Support sample mode, quality control mode, continuous statistics mode to meet individual needs.


Non-contact benchtop spectrophotometers are widely used in cosmetics, fruits and vegetables, food hygiene, plastic electronics, paint and ink, printing, ceramics and other industries. Its unique innovative design not only provides non-contact measurement solutions directly from the production line, but also ensures stable and high-precision measurement results.
