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.
 

1. Novel and fashionable appearance design based on ergonomics

The position of the hand grip and the measurement button are carefully designed to meet different gripping habits. The smooth and fine surface is derived from the art of high-precision appearance processing.


2. 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.

3. 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.

4. Grating Spectrophotometric technology

Using grating spectrophotometric technology, it has higher resolution and makes color measurement more accurate.

5. Place the base safely to ensure that the whiteboard is not dirty

7. 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).
 SuperCharge
 

8. 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.
Single Aperture

9. Excellent inter- instrument error and repeatability to ensure the consistency of measurement data of multiple equipment

 

10. Diversified data display

Spectrocolorreader CR7 (basic) can intuitively display reflectance (reflectance at a specific wavelength specified by the user), sample chromaticity value, color difference value/graph, pass/fail result, color simulation, color offset and other data .It is convenient to view and also greatly improves the user's work efficiency.
Diversified data display


CR7 Spectrocolorreader is useful for controlling the color difference for delta E, and widely used in the fields of plastics, electronics, paint, ink, textile, clothing, printing and dyeing, food, medicine, cosmetics, industries, scientific research institutes, schools and laboratories.

FAQs About CR7 ColorReader

Techniques of measuring color are visual color comparison, colorimetry (with colorimeters) and spectrophotometry (measuring spectral reflectance), and image analysis. Both techniques measure the reflection or absorption of light by materials and are commonly quantified. Therefore standardized in color spaces such as CIELAB or RGB.

Color is a qualitative and quantitative measure. Qualitatively, it can be characterized by the hue, the saturation, and the brightness. It is quantified in terms of color spaces, such as L*a*b* or RGB, in terms of numerical values based on devices such as colorimeters or spectrophotometers.

CIELAB L*a*b* values are the most standardized units in the use of color measurement. These determine values of lightness (L*), red-green (a*), and blue-yellow (b*). The color differences between the two samples can be measured through ΔE.

Color measurement methods involve visual approximation (against color charts), colorimetry (by means of filters and detectors), spectrophotometry (a more detailed spectral analysis), and image analysis by computer. These are color measurement methods that are applied in the laboratory, production, and quality assessment.

The color may be quantified in L*a*b* (CIELAB units), RGB values, CMYK (printing), and ΔE (color difference). Colorimetric assessment measures also apply spectral reflectance and absorbance (A), particularly in liquids and solutions.
