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 △E is less than 0.07, actually more in 0.03~0.06.
• Portable structure design which is more conductive to keeping the instrument stable when using.

3. Convenient and Fast Locating

• Illumination locating is a fast, simple and convenient locating function which is the original function by 3nh.

4. PC Software—Realize More Function Expansion

• 3nh has the intellectual property of PC software. The corresponding software serial number and
• password protection are configured in 3nh colorimeter.
• Be able to perform color difference analysis, color difference cumulative analysis, chromaticity index, color sample database management, simulating object color, etc.

5. Advanced Power Management Design

• 3nh is the first enterprise using high capacity Li-ion battery in colorimeter.
• 3nh 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.
