Description
Overview
GAOTek Spectrophotometer with 360-1000 nm Range and Backlit LCD is a portable desktop spectrophotometer designed with independent core spectroscopic technology. It features built-in silicon photodiode array sensors (40 groups in double rows) and an imported whiteboard for enhanced measurement speed and operational convenience. Its rotating and pressing structure simplifies testing, offering accuracy with repeatability Δ Eab controlled within 0.05 and inner errors Δ Eab within 0.15. This high precision makes it ideal for lab-based color analysis and transfer tasks. The device is equipped with a Φ 30 mm diameter measurement aperture, enabling precise color measurement and quality control for large samples. It is widely applicable across industries such as textile and garment printing, dyeing, plastic electronics, and ceramics. Additionally, it supports fluorescence sample measurements for enhanced versatility.
