Introduction:
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.
1. Adopt full-band balanced LED light source
The full-band balanced LED light source ensures sufficient spectral distribution in the visible light range, avoids the lack of spectrum of white LEDs in a specific band, and ensures the measurement speed of the instrument and the accuracy of the measurement results.
2. Silicon photodiode array (double 24 array) sensor
The dual-24 array sensor with larger area has strong light but not saturate, higher sensitivity of low light and wider spectral response range, which ensures the measurement speed, accuracy, stability and consistency of the instrument.Mastering the core technology and fully compatible with international standards.
3. Grating Spectrophotometric technology
Using grating spectrophotometric technology, it has higher resolution and makes color measurement more accurate.
4. Place the base safely to ensure that the whiteboard is not dirty. Professional whiteboard, a promise that will never change color forever.
5. Fast charging
Special fast charging method, low-voltage reminder to charge or use of off-hours to charge, to ensure the capacity and life of the battery (note: frequent repeated charging of the battery is more harmful).
6. Single measuring aperture can accurately meet the needs of sample measurement
Spectrocolorreader CR7 (basic) is equipped with a Ø8mm platform aperture to meet your sample measurement needs.
7. Excellent inter- instrument error and repeatability to ensure the consistency of measurement data of multiple equipment
8. Excellent inter- instrument error and repeatability to ensure the consistency of measurement data of multiple equipment.
