Differential spectrum engine improves overall measurement performance
The light input of the sensor is increased by 50%, thespectral resolution is increased by 30%, the signal-to-noise ratio is higher,the repeatability, the difference between the instrument, and the data ishighly consistent with the data of the standard instrument, theinter-instrument agreement can reach to 0.12, and the repeatability can reachto 0.005. The relevant technologies are protected by Chinese invention patents.
Doubleoptical path design improves repeatability accuracy
repeatability accuracy dE*ab≤0.005
The dual optical path design monitors the energyfluctuation of the light source while measuring the sample signal, reducesinterference during measurement, obtains higher measurement stability, andimproves the measurement repeatability index of the instrument to dE*ab≤0.005. The high standard of measurement speed, accuracy, stabilityand inter-station difference is guaranteed. The relevant technologies areprotected by Chinese invention patents and American invention patents.
Innovative 1nm resolution grating spectroscopy technology
Innovation is the soul of CHNSpec. After nearly 10 years of dedicated research, the grating combined array sensor made by the innovative MEMS process makes the color measurement more accurate on the basis of 1nm spectral resolution, once again leading the industry innovation direction and greatly improving the technical performance of the product. The relevant technologies are protected by Chinese invention patents.
Excellentinter-instrument agreement：dE*ab≤0.12，
Highrepeatability accuracy：dE*ab≤0.005，ensure accurate data transfer between factories
Self-developedfluorescence calibration technique
Automatically adjust the UV intensity, and ensure that the instrumentvalue is highly consistent with the reference value when measuring thefluorescent material.
High precision automatic calibration
Advanced automatic calibration technology greatly improves long-termrepeatability of instruments. Under constant temperature, the dE*ab of day 1and day 30 can still reach 0.01. At any temperature change from 0℃ to 40℃, dE*ab can reach lessthan 0.1.
Long-termrepeatability curve at constant temperature

Easily measure samples of many shapes with a variety of measuring apertures
Four test calibers, free to switch
Support measurement in reflection mode: solid, powder, non-transparent liquid
Support measurement in transmission mode: glass, film, transparent liquid
Configure high-definitionpreview camera
The clarity of the camera has been significantly upgraded, from the original 400dpi to 1400dpi. When observing the sample, the clarity has been improved by 350% and brightness calibration algorithm has been used to truly restore the color of the ultra dark sample.
