Spectrocolorreader CR7 (Basic)-3NH

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

6. Professional whiteboard, a promise that will never change color forever

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

2. In which condition, manual white and black calibration and auto calibration are required for NH310?

a. It’s needed to perform manual calibration for NH310 when first starting.

b. In the subsequent starting, NH310 will perform auto calibration at startup. No need to perform manual calibration.

c. Suggestion: it’s best to perform manual calibration once a week or when NH310 measured data is not accurate.

3. Can the colorimeter measure light-transmitting materials (such as colored glass and film)?

Since part of the light will pass through the light-transmitting materials, the colorimeter is not suitable for color measurement of such kinds of materials; however, when place a pure color material with uniform texture under the light-transmitting material, we can measure the color difference between the standard and the sample.
