  • High-End Brand of Domestic Colorimeter 

    NH300 is a mainstream brand colorimeter introduced by Captech 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!

    The Preferred Solution for Color Quality Control Management

    NH300 high-quality portable colorimeter has adopted multi-channel color sensors of international brands, more stable IC platform as well as efficient and accurate algorithms 

    to provide users with accurate and fast color management and application. CNH300 is also designed with 

    ergonomics and humanized operation and it has applied for a number of patents. CNH300 is a multifunctional 

    colorimeter with high quality and competitive price. Captech insists on independent research whose

     technology innovation is unique in color management field. NH300 is the most convenient colorimeter

     for users.


    1. Leading Humanity Design and Convenient Operation

    · Auto White and Black Calibration at Startup

    · Structure Design in line with Ergonomics

    · Fool-style Operation Interface

    2. Stable Measurement Performance

    · The average fluctuation of E is less than 0.08, 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 Captech.

    4. PC SoftwareRealize More Function Expansion

    · Captech has the intellectual property of PC software. The corresponding software serial number and

     password protection are configured in Captech 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

    · Captech is the first enterprise using high capacity Li-ion battery in colorimeter.

    · Captech 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.
