Overview
KINGWELL JZ-350 color difference meter is a new Handheld color difference meter developed according to multinational standards. The main components are imported products, which have good advantages in measurement Stability and durability. The instrument integrates a variety of display modes, including L*a*b*、L*C*H*、XYZ、∆E*ab、∆（L*a*b*）、∆（L*C*H*）、∆XYZ, and has four Available Light Sources.
The JZ-350 color difference meter is developed and produced in accordance with international CIE1931, 1976 and other relevant standards and JJG595-2002 national standards. The main parts are all imported from Japan and Germany, and it has the characteristics of stability, durability and economy.
Features
1. KINGWELL JZ-350 color difference meter has three Operating languages to switch freely, Menu Operating interface is easier to control
2. A variety of Illuminant and color space modes to meet the special requirements of different measurement conditions
3. Standard with whiteboard correction and zero correction, measurement data is more accurate and stable
4. Large storage space, capable of storing 1500 sets of data, which can be viewed, retrieved, and uploaded to the computer at any time
5. Professional color quality software can assist in color scheme analysis and quality control
6. Purchase a micro printer. Through the micro printer, data can be output on site without connecting to a computer
7. Color quality software can analyze and communicate color charts and data
Principle
The color difference meter adopts 45 °/0 ° illumination mode. Measurement light sources include D65, D50, F11, and C. Measurement time is about 2 seconds, and the measurement diameter is φ 8mm. Repeatability Standard Deviation < unk > E * ab ≤ 0.08 (Measurement condition: use standard whiteboard to measure 30 times to take the average value). The observation angle is CIE 2 °/10 °. Color difference formulas include L * a * b *, L * C * H *, XYZ, < unk > E * ab, < unk > (L * C * H *), < unk > XYZ. Data storage can store 50 sets of Standard values, each set of Standard values stores 30 sets of color difference data.
