Home Colorimeter
ST-PC31 High-End Brand of Domestic Colorimeter ST-PC31 is a mainstream brand colorimeter introduced by Stalwart which has synthesized the advantages of ten more traditional imported colorimeters and has experienced ten thousands tests and applied many innovative technologies. Accurate, Stable, Exquisite and Affordable.
1. Leading Humanity Design and Convenient Operation
Auto White and Black Calibration at Startup
Structure Design in line with Ergonomics
Easy-to-use Operation Interface
2. Stable Measurement Performance
The average fluctuation of ΔE is less than 0.06, actually more in 0.03~0.06.
Portable structure design which is more conductive to keeping the instrument stable when using.
3. Flexible and Accurate Locating
Camera locating can solve the problem of locating a small area. The minimum width of locating is 4mm.
Illumination locating is a fast, simple and convenient locating function which is the original function by Stalwart.
4. More Measurement Modes
Three measuring apertures for more circumstances.
Five color spaces for more color schemes selection.
Three light sources for more circumstances.
5. PC Software—Realize More Function Expansion
Stalwart has the intellectual property of PC software. The corresponding software serial number and password protection are configured in Stalwart colorimeter.
Be able to? perform color difference analysis, color difference cumulative analysis, chromaticity index, color sample database management, simulating object color, etc.
6. Advanced Power Management Design
Stalwart is the first enterprise using high capacity Li-ion battery in colorimeter.
Stalwart Li-ion battery can be repeatedly charged which will save cost. Meanwhile, it can measure more than 3000 times on one charge to ensure the stability of long time measurements.
