Overview
The DONGRU DR200 Portable color difference meter is a precision Color measurement device with LED Blu excitation and D65 Measurement light source. Repeatability up to 0.08Delta E * ab and rechargeable Li-Ion battery for more than 3000 measurements on a single charge.
Features
1. Humanized design and easy operation: one-click test, human body mechanics structure, silly Operating interface.
2. Stable measurement performance: Delta E is less than 0.08, Portable structure design is conducive to maintaining the stability of the fuselage.
3. Convenient and fast positioning: Equipped with patented lighting positioning function and cross positioning.
4. PC-side software function extension: with genuine software serial number, support color difference analysis, cumulative analysis, chroma index, color sample library management and Color simulation.
5. Professional Power Management: High-capacity rechargeable lithium-ion battery, no need for repeability purchase, to ensure long-term measurement Stability.
Principle
The color difference meter adopts an 8 °/D measurement geometry structure. After the blue light source of LED is irradiated to the measured object, the reflected light is received by the photodiode array Sensor. The instrument converts the received optical signal into an electrical signal, and calculates it in the CIEL * a * b * and other Color spaces according to the CIE 10 ° observation angle standard, and finally obtains the color coordinate value of the sample and the color difference value with the standard sample.
