Laboratory Colorimeter is the second colorimeter I’ll talk about today.

The colorimeter is an instrument to measure the color. It is usually used with chemical analysis by comparison of a liquid's color with standard colors. In this essay, I won’t talk about the definition of colorimeter; there are three types of colorimeter I want to introduce. By the way, I don’t like advertisement, either. So, there is only introduction in my essay.

The Sucroflex reflectance colorimeter is the first one I want to talk about. As we all know, sugar’s color is one of the most eye-catching quality factor of sugar, which may vary from brilliant white to yellow-brownish tones. Also, this colorimeter is used to the color classification of white sugar. International Commission for Uniform Methods of Sugar Analysis (ICUMSA) has already defined a color type scale for color grading of the white sugars. It includes a limit from 0 to 6.The 0 stands for maximum whiteness of sugar, while 6 corresponds to minimum whiteness of sugar.

Laboratory Colorimeter is the second colorimeter I’ll talk about today. This is a portable device .You can find many hand-held device like it in the market. And these types with battery operated are for water and environment testing. This colorimeter is used for measuring the absorbance of a solution at a particular wavelength of light. Its measurement accuracy is also increased. Now, the achievement in it is the results and test data could be stored into memory. There are  its functions below: self-contained, save money(because it is fast and easy to use colorimeters ,even spend just pennies a test to measure the concentration of compounds),automatic wavelength.

The last one is also the most important one. There are three series models with automatic wavelength selection of the DR/800 Portable Colorimeter. The standard features are showed:

Rugged: waterproof, dustproof, worry-free, shockproof (designed to meet IP67 standards) 

Affordable: select a complete portable laboratory or choose the instrument you need

Powerful: full data logging and RS232 interface capabilities 

Batteries-/Accu operation possible, Real-Time-Clock, integrated Timer, Data Memory with 100 measuring values and automatic Auto Off-Function. Wavelengths: 420 nm, 520 nm, 560 nm and 610 nm.

Compact: true hand-held analysis, for use anywhere 

Simple: menu-driven, step-by-step analysis

There is no doubt that all of its features are good. But the best advantage of this colorimeter is that it is easy to control.
