Overview
DS-300 Colorimeter is a portable color difference meter under the DOHO brand, model DS-300. It adopts independent spectroscopic core technology to ensure the accuracy of color difference Delta E while ensuring the long-term accuracy of absolute values L, A, B, which is convenient for international and domestic standard Measurement at any time. The instrument has built-in silicon photodiode array (double column 32 groups) sensors and imported whiteboards. Repeatability Delta E * ab can be controlled within 0.06, taking into account Measurement speed and operation convenience. It supports fast color difference measurement and judgment with or without connection to PC software.
Features
1. Adopt full-band Balanced LED light source to ensure sufficient Light spectrum distribution in the visible range to ensure Measurement speed and accuracy of results.
2. Adopting internationally accepted D/8 lighting observation conditions and SCI/SCE synthesis technology, it is suitable for a wide range of applications.
3, ergonomic design, comfortable grip, and equipped with automatic measurement device, portable and easy to use.
4. Using a larger area of silicon photodiode array (dual 32 array) Sensor, with high Sensitivity, wide Light spectrum Response Range, to ensure Measurement speed, accuracy, Stability and conformity.
5. Each instrument has been verified and tested before leaving the factory, and the data is traced back to the National Measurement Institute to ensure the credibility of the test data.
6. Using imported yellowing-resistant standard whiteboard and ETC real-time calibrating technology, each test guarantees accuracy and Repeatability.
7, built-in camera view positioning function, real-time observation of the measured area, improve measurement efficiency and accuracy.
8. With SQCX quality management software, it supports Color data management, color difference comparison, report generation and customized Color management.
Principle
The DS-300 Colorimeter uses a planar grating spectroscopy method and uses a combined full-light spectrum LED light source for D/8 (diffuse illumination, 8 ° direction reception) illumination. After the ray of light irradiates the sample, the reflected light is received by the silicon photodiode array (dual column 32 group) Sensor through the Optical inspection system, and analyzed as Light spectrum data. The instrument supports both SCI (including mirror reflection) and SCE (excluding mirror reflection) Measurement modes. Color space and color difference indicators are calculated by analyzing Light spectrum data to achieve accurate color measurement and color difference judgment.
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 it on and ensure that the instrument has sufficient power.
2. Select the appropriate measurement caliber according to the tested sample (φ 8mm platform caliber or φ 8mm tip caliber).
3. Use camera viewfinder positioning or stabilizer positioning to align the measurement port with the center of the target area.
4. Measurement mode (single measurement or average measurement) and required observation light source, Color difference formula and other parameters.
5. Trigger the measurement, the instrument completes the measurement and displays the result within about 1.5 seconds (about 3.2 seconds for the simultaneous test of SCI/SCE).
6. You can view the data directly through the instrument screen, or connect to the PC-side SQCX software for data analytics, storage and management.
Notice
• The instrument should be used and stored under the conditions specified in the operating environment (0~ 40 ℃, 0~ 85% RH, no condensation) and storage environment (-20~ 50 ℃, 0~ 85% RH, no condensation).
• The use altitude should be less than 2000 meters.
• When measuring, ensure that the measurement diameter is closely fitted with the measured surface to avoid light leakage affecting the results.
• Regularly calibrate with a standard whiteboard to ensure measurement accuracy.
• Avoid severe vibration or impact on the instrument.
• When cleaning the instrument, wipe it with a soft dry cloth to avoid the use of corrosive cleaners.
• Charge in time when the battery is low to ensure the number of measurements and instrument performance.
