Description
Overview
GAOTek’s Portable High Precision Spectrophotometer is a portable spectrophotometer developed by using its own core technology of spectroscopy. It uses a built-in silicon photodiode array (dual-row 24 groups) sensor, an imported white board, and the repeatability ΔE x ab can be easily controlled within 0.03. Its powerful performance configuration and excellent inter-instrument error make color measurement more professional, while also ensuring the consistency of measurement data of multiple devices. It considers the measurement speed and the convenience of operation at the same time. The color can be controlled through the PC-side software, and it can also be seamlessly connected to the mobile device through Bluetooth. It greatly expands the application space of the colorimeter and makes the traditional colorimeter glow with a different application charm.
