1.Leading Humanity Design and Convenient Operation
One-touch access to measurement interface
Structure design in line with ergonomics
East-to-use operating interface
2.Stable Measurement Performance
The repeatability E is 0.08.
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 which created 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.
