As a saleswoman of 3nh company, customers always ask me why we need to choose spectrophotometer neither than colorimeter. What's the difference between colorimeter and spectrophotometer?
I always tell them spectrophotometer is more preciser and stable, because they use 400-700 nm wavelength and they have reflectance rate. Of course, they have more functions.
Colorimeter and spectrophotometer is both good to measure delta E and get a good test result, but spectrophotometer can compare with many other brands instrument, such as BYK, Datacolor, X-rite, Monilta etc. If customers need absolute LAB value, I think spectrophotometer is better.
Here is another explaination from internet:
A colorimeter measures the absorbance of a particular wavelength by a solution. It is usually used to determine the concentration of a known solute in a known solvent through the application of the Beer-Lambert law (absorbance is proportional to concentration).
A spectrophotometer is related to a colorimeter but may be used to scan across a spectrum of wavelengths. It also measures slightly different properties. A spectrophotometer usually measures transmittance (which is related to absorbance) or reflectance of solutions, transparent or opaque solids, such as polished glass, or gases. Hence a spectrophotometer is of broader application than a colorimeter. It can perform the same functions as a colorimeter, but it can also do more.
Because a
colorimeter is much simpler than a spectrophotometer, it is usually much cheaper. Some models of colorimeters are very portable and retail for a bit over US$200 ($200-$1800 typically) while a spectrophotometer is almost always a lab bench size unit and will usually cost US$2000 and up ($2000-$6000 typically).
