Description
Overview
GAOTek Non-Contact Spectrophotometer is a color measuring instrument that adopts the standard of 45/0° (45°circular uniform illumination 0°reception). non-contact test between test probe and tested sample, to achieve liquid and sauce, powder and other non-contact precision color measurement. The simple probe design allows this product to be placed anywhere on the automated production line for precise color measurement and color quality control. It is widely used in cosmetics, fruits and vegetables, food hygiene, plastic electronics, paint and ink, printing, ceramics and other industries. It can be used for fluorescent sample measurement. Its unique innovative design can not only provide non-contact measurement solutions directly from the production line but also ensure stable and high-precision measurement results.
