1. Leading Humanity Design and Convenient Operation

 a. Auto White and Black Calibration at Startup

 b. Structure Design in line with Ergonomics

 c. Easy-to-use Operation Interface


2. Stable Measurement Performance

a. The average fluctuation of E is less than 0.06, actually more in 0.03~0.06.

b. Portable structure design which is more conductive to keeping the instrument stable when using.


3. Flexible and Accurate Locating

a. Camera locating can solve the problem of locating a small area. The minimum width of locating is 4mm.

b. Illumination locating is a fast, simple and convenient locating function which is the original function by Lab-kits.


4. More Measurement Modes

a. Three measuring apertures for more circumstances.

b. Five color spaces for more color schemes selection.

c. Three light sources for more circumstances.


5. PC Software—Realize More Function Expansion

a. Lab-kits has the intellectual property of PC software. The corresponding software serial number and password protection are configured in Lab-kits colorimeter.

b. 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

a. Lab-kits is the first enterprise using high-capacity Li-ion battery in colorimeter.

b. Lab-kits 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 measurement.
