Feature
Large measuring aperture, higher precision
As it can measure larger area with its large 20mm measuring aperture, the device ensures higher precision on the test results as it acquires more even color data when measuring textured or rough surface materials.
Touch screen makes measurement convenient
The device adopts a 3.5-inch IPS color capacity touch screen, no need to operate by pressing button. It offers smooth user operation experience and interactive interface, simple operation.
Built-in multiple electronic color charts
The device provides multiple sets of electronic color charts applicable for many industries (RAL, Pantone, NCS, etc.) can quickly match 3 closest serial numbers in the color charts with precision rate over 90%, keeping your hands free from carrying heavy color charts.
Large storage space
Massive storage space, users can create personalised color databases and easily enter industry-specific color card information.
CIE Lab color deviation indication
Only two clicks on the screen are needed to complete a color difference measurement. The colorimeter provides the color deviation indication of the three color channels of CIE Lab and assistance for color mixing.
Various ways to complete color comparison
You can enter the values of the standard color in the color compare interface or just add from the personal color chart and standard color chart. No need to worry about ageing and discolouration of samples.
Achieve more efficient quality control
In the color difference comparison mode, you can set a color difference threshold, the colorimeter shows pass/fail, ΔL, Δa and Δb — especially for rigorous industrial settings.
Good Repeatability
Good repeatability, ΔE*ab≤0.03, the colorimeter can pass the inspectation of authoritative metrology institute.
Equipped with mobile App and PC software
The instrument can be used with mobile APP or PC software for online measurement, covering Android, iOS and Windows systems, to help users to data color management and generate test reports.
Support multi-channel color sharing
Enterprise users can import and export color data through the APP or PC software, manage their own color card information library and color formulas, and share the data through WeChat, QQ, email, etc. to the company or customers.
Multiple color spaces and color difference formulas
Provide multiple color spaces and color difference formulas for different industries, including Lab, LCh, ΔE*ab and others.
Spectral reflectance curves
Provides professional spectral reflectance curves from which the user can obtain information on the hue, saturation and shade of the sample color.
Equipped with measurement positioning board
The colorimeter is equipped with a measurement positioning board to meet the needs of precise alignment, and make the measurement more accurate.
Whiteboard calibration
The bottom cover integrates a calibration white tile, so there is no need to worry about losing it. No need for tedious operation.
Easy to carry
Smart and portable, easy to store and carry; stable body, ergonomic design, easuring colors anytime, anywhere.
Advanced color sensor, Outstanding quality
The colorimeter adopts chip-level color sensor AS7261 newly launched by ams AG, whose precise XYZ tristimulus color sensing function simulates the human eye response curve of the standard observer defined in the CIE1931 and CIE1976 color systems.
Full spectrum LED light source
Adoption of full-spectrum LED light source ensures sufficient spectral distribution in the visible range, avoiding the spectral deficiency of white LEDs in specific wavelength bands.
45°/0 annular illumination
The instrument adopts 45/0 annular illumination, which eliminates the dependence on direction, can effectively eliminate the error between human eyes and colorimeter caused by the texture on the sample surface, and minimize the influence of texture.
