CR7 realizes the two-in-one spectrophotometer and spectrocolorreader, easy to use and not expensive. It is a masterpiece that integrates high precision, high performance, and high cost performance.
The CR7 (basic) is a portable spectrophotometer developed by 3nh 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*ab can be easily controlled within 0.1. CR7's powerful performance configuration and excellent inter-instrument error make color measurement more professional, while also ensuring the consistency of measurement data of multiple devices.
