3nh New Handheld Spectrophotometer Colorimeter ST-700 Five Apertures for Color Difference Testing
The handheld spectrophotometer ST-700 is designed to accurately and quickly capture the surface color of objects. No matter what complex lighting conditions, it can accurately lock and restore the true color of the physical surface, providing you with an efficient and convenient color management experience.
The handheld spectrophotometer ST-700 is widely used for precise color measurement and quality control in industries such as plastic electronics, paints and inks, textile and clothing printing and dyeing, printing, and ceramics. It is not only an expert in color measurement, but also your right-hand partner in the world of color. Whether in quality monitoring, color data management or multi-scenario applications, it can provide excellent performance and accurate measurement results.
Product features of spectrophotometer ST-700
1. Combined full-spectrum LED + UV light source
Integrated full-spectrum LED and UV light source to ensure uniform distribution of the spectrum in the full band from visible light to ultraviolet light, eliminate errors caused by spectrum loss, and significantly improve the integrity of color measurement.
2. Large-area dual-array sensor
The large-area dual 40-array sensor is used to effectively solve the problems of strong light saturation and weak light detection, and has a wider spectral response range, making the measurement more accurate and stable.
3. Five-aperture design
The instrument is equipped with five measuring apertures: 5mm platform + 5mm tip + 10mm platform + 10mm tip + 1*3mm. The measuring aperture can be switched freely according to the sample.
4. Framing and positioning function
The instrument has a built-in camera for framing and positioning, which can monitor the measurement location in real time to ensure the effectiveness of the test point and the accuracy of the test results.
5. Non-contact automatic calibration
The instrument is equipped with an intelligent calibration base and a non-contact automatic whiteboard calibration system, so that each measurement can reach laboratory-level accuracy and ensure the accuracy of the measurement results.
6. Rich color index
In addition to the commonly used color index measurement, it can also provide other diversified color indexes such as spectral reflectance, whiteness, yellowness, hiding power and color density to meet the needs of various industries.
7. Powerful display and interactive capabilities
Equipped with a 3.5-inch true color capacitive touch screen, it can display a variety of color indicators such as spectrum graphs, color difference values/graphs, color simulation and color deviation, and achieve fast and accurate color analysis and judgment.
8. Excellent repeatability and inter-device difference
Repeatability ΔE*ab≤0.024, inter-device difference ΔE*ab≤0.22, ensuring high consistency of measurement results between multiple devices, safeguarding color quality control in large-scale production.
9. Strong portability, suitable for multi-scenario measurement
Based on ergonomic design, it is compact and portable, and equipped with a rechargeable lithium battery, making it suitable for precise laboratory measurement and also convenient for flexible application in production sites.
10. Support multi-system operation
The instrument supports Android, IOS, Windows, WeChat applet, and Hongmeng system, realizing mobile and cloud-based color data management and sharing.
