Description
Overview
GAOTek non contact benchtop colorimeter spectrophotometer is a colour measuring instrument with 45 or 0 optical geometry (45 ring to shaped illumination, vertical viewing), to achieve precise non to contact measurement between the measuring probe and the sample like liquids, sauces, powders, etc, which is developed by 3nh independently with independent intellectual property. Non to contact benchtop spectrophotometer can be applied for accurate colour analysis and transmission in laboratories and R & D industries, it can also be used for accurate colour measurement and quality control of automated production lines, it is widely used in cosmetics, fruits and vegetables, food hygiene, plastic electronics, paint and ink, printing, ceramics and other industries, and also for fluorescence sample measurement. Its unique innovative design can not only provide non to contact measurement scheme directly from the production line, but also ensure stable and high to precision measurement results. Non to contact spectrophotometer will not touch the sample in the measurement process, to prevent damage to the sample, but also to avoid cross contamination.
