Threenh Technology with excellent after sale service, Generally, Our Spectrophotometer instrument warranty is one years(Additional support period of 3 years). Within the warranty period, we can offer technique support and parts to parts change, necessarily, our engineers may go to your place for better support. Our instrument have professional After-sales Dept, if you have any technical problem or question with our goods welcome to contact us.

To answer this question, you first need to clarify your specific needs: 

• Is it for simple color quality control (QC)?

• To coordinate with supply chain color management?

• To monitor on-line color stability?

• Do you require computer color matching or production color correction?

• What is your budget?

• Systematic supervision and evaluation of color performance in dyed products?

If you aren’t fully clear about your requirements at the initial stage, our color management engineers are ready to communicate with you. We will recommend solutions tailored to your needs. When conditions permit, we can provide prototype demonstrations and trial testing to ensure the instrument meets your practical application requirements.

The accuracy of colors is determined by comparing the values of the colors (L*a*b*) of a sample with a standard reference sample using tools such as spectrophotometers. The variation is measured as ΔE. The smaller the value of ΔE, the more accurate, the nearer to the target color.

The CCC is much like the CAC yet it frequently has advanced programmable lighting, sophisticated electronic control systems that allow for light source switching, and advanced visual testing.

They provide accurate and repeatable assessments of color in various settings for the purpose of avoiding inconsistencies in mismatched items and ensuring steady production or branding.

You can choose a colorimters depending on the substrate you are measuring the color of, whether it is opaque, translucent or transparent. In short, you can consider the following factors for choosing the right 3NH colorimeter for your needs: Sample Opacity, Physical Form, Optical Properties needed, Measurement Methods required, Scales and Indices needed, Instrument Standards Conformance (ASTM/ISO/Other), Instrument Geometry, Instrument Performance, Location (laboratory, portability, in-process) and Sample Handling requirements.

By systematically addressing these factors, you can select a colorimeter that optimizes accuracy, efficiency, and value for your specific application.Learn more from our ultimate guide on colorimeter selection. If unsure, consult the 3NH manufacturer for personalized recommendations based on your sample and workflow.

A colorimeter measures the amount of light and the wavelength that is absorbed by a solution. It is a sign that colored compounds are present and the level of their concentration. It is applied in the laboratory and industry to check the concentrations of chemicals, the color of products, and purity.

Colorimetry is a method that applies color intensity to ascertain the chemical concentrations. It is founded on Beer-Lambert Law, whereby the absorbance at a given wavelength is proportional to the concentration. It is popular in environmental and biochemical testing.

Use our 3nh company approved light. Replace all of the same type together and recalibrate to keep consistent color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses
