Linshang LS173 Portable Handheld Colorimeter High Precision Color Analyzer with 3.5-Inch Touch Screen for Paint Plastic Metal

Features:
- 3.5-inch ultra large touch screen, easy to operate, simple and easy to understand interface, with only two clicks and results in one second.
- Providing color bias prompts and assisting in color adjustment can eliminate the influence of human factors on color judgment.
- Automatically determine whether the color difference is qualified, especially suitable for factory QC testing; Detect the deviation between the sample color and the standard color. After setting the color difference ΔE threshold (0.1-50 optional), it can automatically determine whether the color difference is qualified.
- Built in multiple electronic color cards, color measurement can quickly match the closest 3 color card numbers from multiple industry standard electronic color card libraries, making it convenient to quickly find colors.
- Support the entry of industry-specific color cards and the establishment of one's own electronic sample library. It can store a massive amount of colors and input industry-specific color cards for paints, fabrics, coatings, etc., without the need to carry or browse paper color cards, avoiding aging and discoloration of standard samples.
- Professional spectral reflectance curve display: Based on the reflectance curve, the sample's hue, saturation, brightness, etc. can be determined to provide assistance for color matching, avoiding the phenomenon of same color but different spectra.
- Built in 4 industry wide whiteness/yellowness testing standards, easy to measure object whiteness/yellowness.
- High precision △E*ab≤0.03, in compliance with national first level metrology standards.
- Built-in lithium battery, capable of continuous testing up to 1000 times when fully charged.
- The base comes with a calibration whiteboard for convenient design.
- Silicone buttons, comfortable grip, ergonomic.
- Equipped with LED white light source, the test is not affected by external light.
- Screen angle of 30° provides a perfect viewing angle for easy reading.
- Type-C universal charging interface, easy to charge.
