Overview
DS-100 spectroscopic color difference meter is a portable spectroscopic color difference meter under the DOHO brand, model DS-200. It uses independent spectroscopic core technology and is a high-level color difference meter under spectroscopic architecture, which not only ensures the accuracy of color difference Delta E, but also ensures the long-term stability of Color absolute values L, A, B. The instrument adopts a built-in silicon photodiode array (dual column 24 groups) sensor and imported whiteboard. Repeatability Delta E * ab can be controlled within 0.1, and color difference measurement and judgment can be quickly carried out without connecting to a computer.
Features
1. Ergonomic design, smooth appearance, comfortable grip, suitable for continuous inspection work.
2. Adopt full-band Balanced LED light source to ensure sufficient Light spectrum distribution in the visible range to ensure accurate Measurement speed and results.
3. Silicon Photodiode Array (Dual 24 Array) Sensor with High Sensitivity and Wide Light spectrum Response Range to Ensure Measurement speed, Accuracy, Stability and conformity.
4. Measurement verification reports are provided for each instrument, and the measurement data is traced back to the National Measurement Institute to ensure the credibility of the test data.
5, using imported standard whiteboard and ETC real-time calibrating technology, Optical inspection system built-in standard whiteboard, each test to ensure reliable accuracy and Repeatability.
Principle
The DS-100 spectroscopic color difference meter adopts D/8 (diffuse illumination, 8 ° direction reception) illumination mode and meets the relevant Optical inspection standards. It irradiates the sample by combining a full Light spectrum LED light source, splits the light with a planar grating, and receives the Reflection spectrum by a silicon photodiode array (dual column 24 groups) Sensor. Light spectrum data in the wavelength range of 400~ 700nm is systematically analyzed to calculate the color space value (such as CIE LAB) and color difference value of the sample, so as to achieve accurate color measurement and comparison.
Applications
Plastic electronics, paints inks, Spinning & weaving garment printing, printing, Pottery and porcelain
Standards
CIE No.15、GB/T 3978、GB 2893、GB/T 18833、ISO7724-1、ASTM E1164、DIN5033 Teil7
Steps
1. Turn on the instrument power supply.
2. Use the stabilizer to locate and align the measurement aperture with the sample to be tested.
3. Measurement mode (such as single measurement or average measurement) is selected as needed.
4. Trigger the measurement and read the chromatic value, color difference value or pass/fail result on the display after about 1.5 seconds.
5, measurement data can be automatically stored and exported through the USB interface.
Notice
• Please use the instrument in the operating environment (0~ 40 ℃, 0~ 85% RH, no condensation, altitude below 2000m).
Store in an environment of -20~ 50 ° C and 0~ 85% RH (no condensation).
The instrument adopts imported standard whiteboard, which is resistant to yellowing and can be wiped, but still needs to be kept clean to ensure long-term accuracy.
• The instrument has a built-in lithium battery, please use it reasonably to ensure Battery life.
The lifetime of the lighting source is about 5 years or more than 3 million measurements, which may affect the performance.
