The Preferred Solution for Color Quality Control Management

NH310 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. NH310 is also designed with ergonomics and humanized operation and it has applied for a number of patents. NH310 is a multifunctional colorimeter with high quality and competitive price. 3nh insists on independent research whose technology innovation is unique in color management field. NH310 is the most convenient colorimeter for users.

NH310 colorimeter has many functions which can measure color fastness, whiteness (Hunter and ISO R457), Yellowness (YI), etc. However, we can also customize the following light sources for customers.

It's used to compare color difference in plastic, electronic, painting, coating, ink, texile, garment, printing, dyeing, food, medical, cosmetic industries and institutes, schools and laboratoris. 

The repeatable accuracy of NH310 is: DE<0.08. 

NH310 adopts a wide range of innovative technologies 

1. Both camera locating and illumination locating 

2. Built-in standard white calibration plate; Automatic calibration at startup 

3. Optional 8mm extended aperture, available for measuring concave surface 

4. Configuring 8mm & 4mm apertures which can measure colors of any item

No. 1 Camera locating and illumination location (NH310) 
No. 2 Built-in white plate; Automatic calibration at startup (for NH310) 
No. 3 Extended aperture (optional), available for measuring concave surface

3nh analyzed the parameters from Japan,American and Germany spectrophotometers. The differences of L*ab absolute value between them are within ±1.5. Compared the L*ab value between NS800 and Japan spectrophotometer, when measuring any color objects, the biggest L*ab difference is within ±1.0. This is a breakthrough of 3nh high technology 
which realizes to be fully compatible with international market.

CIE LAB
-L(Lightness)-0 is black,100 is white
-a(Red-Green)-positive values are red; negative values are green and 0 is neutral
-b(Blue-Yellow)-positive values are yellow;negative values are blue abd 0 is neutral

CIE LCH
L: Lightness,value is the same in each scale C:Chroma H:Hue Angle

dE Total Color difference
Delta-E is a measurement used to indicate how much a color deviates from an accepted standards.The higher the dE, the more inaccurate the color.
