Take into account the measurement range, type of samples, needed precision, any relevant standards, and your industry.

The repeatability is an important parameter for the accuracy of the colorimeter. Threenh Technology portable colorimeter for color measurements tandard deviation ΔE*ab is within 0.03 (Measurement condition: the average value of 30 measurements on the white board at an interval of 3s after calibration). Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.

Yes. However, for LED retrofitting to meet industry standards, color- calibrated LED modules must be used for accurate 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

Always a pre-production sample before mass production; Always final Inspection before shipment; 

The most important equation is A = 2εcl, where A is the absorbance, 2 is a constant, ε is the molar absorptivity (L/mol cm), c is the concentration (molL-11), and l is the path length (cm). This can be used to relate the absorbance to the concentration, allowing quantification through colorimetric assays.

The ΔE (Delta E) formula of the CIELAB color space is usually used to measure color difference. The difference is measured in a colorimeter or spectrophotometer to gauge the level of perceptibility of the difference between two samples in terms of L*a*b*.

Haze captures the scattering of light, transmittance measures the light that passes through a said material.

Depending on model and location, delivery time is usually 2-4 weeks for standard models and 4-6 weeks for built- to-order ones. 

Of course! Many portable, battery operated, and lightweight coating thickness gauges are available for on-site and field inspections. They provide quick and accurate results and portable gauges are ideal for construction, automotive, and industrial environments.

There is no generic mathematical formula for gloss value. Rather, it is measured directly with a gloss meter, which compares how strongly reflected light from a sample matches a standard (typically black glass with a known reflectance).
