Description
Overview
GAOTek portable handheld colorimeter is a portable spectrophotometer. It uses a built-in silicon photodiode array (dual-row 24 groups) sensor, an imported white board, and the repeatability E x ab can be easily controlled within 0.1%. 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.
