ST-700D Portable Spectrophotometer
Product Description
ST-700d is an array spectrophotometer developed by 3nh using its own spectroscopic core technology. It uses a built-in silicon photodiode array (40 sets of dual columns) sensors and an industrial-grade MCU. The powerful data processing capability ensures the stability and accuracy of the measurement data. The array spectrophotometer ST-700d can easily control the repeatability ΔE*ab within 0.022, and the inter-instrument error ΔE*ab within 0.2. It can be used for accurate color measurement in various occasions and conditions, and the large-size touch screen can view the measurement results more easily and convenient. The measurement data of the instrument is consistent with other competing products from Japan, the United States, and Europe.
Product Parameters
1. Silicon photodiode array (double 40 array) sensor
The larger area of the double 40 array sensor, the strong light will not saturation, weak light sensitivity and a wider spectrum response range, to ensure the instrument measurement speed, accuracy, stability and consistency, master the core technology, and the international standard of the same platform, complete compatibility.
2. Adopt full waveband balanced LED light source
The full waveband balanced LED light source ensures sufficient spectral distribution in the visible light range, avoids the spectral loss of white LED in specific waveband, and ensures the measurement speed and accuracy of the measurement results.
3. Grating spectroscopic technique
Use Grating spectroscopic technique, with higher resolution, to make the color measurement more accurate.
4. Place the base safely to ensure that the whiteboard is not dirty.
5. Professional whiteboard, a lifetime never change color commitment
6. Fast charging
Special fast charging mode, low voltage to remind charging or use off-duty time charging, to ensure the capacity and life of the battery (note: frequent repeated battery charging more harm).
7. New fashionable appearance design based on ergonomics
The position of the hand holding and the measurement button are carefully designed to meet different holding habits, smooth and fine surface, resulting from the high-precision appearance processing art.
8. Equipped with three measuring apertures to meet the most samples measurement
The Factory configuration of spectrophotometer TS7708 is with ø 8mm flat aperture, ø 8mm tip aperture, ø 4mm flat aperture, ø 4mm tip aperture, ø 1x3mm aperture, a total of five measuring apertures, to meet the most samples measurement.
