subject: Dr 890 Colorimeter: A Must-buy For Your Facility [print this page] More often than not, the color of a substance states the characteristics like taste or chemical properties. When it comes to water, it may be difficult to distinguish between pure water and polluted water, due to its transparent nature. There are a many ways to discover these pollutants and one of them is with the help of colorimetry.
Colorimetry is a unique technique that is used for checking the concentration of colored compounds in a solution. A handy device used for this purpose is known as a colorimeter. It determines the absorbance of light by various colors in different environments. There are many different types of colorimeters, including the color densitometer, which measures the density of primary colors, and the color photometer, which measures the reflection and transmission of color. Most of these devices are digital and portable. The former is used mainly at labs for sampling or educational purposes. The latter is ideal to test I harsh environmental conditions and on site sample testing.
However, not all multiple orsingle parameter colorimetersused for this may be equally efficient. The outcome of these devices has to be consistent in their results as well as accurate. At the same time, it should be able to handle different kinds of water sample with the same power.
One such competent device is the DR 890 colorimeter from Hach.This smart device portable, lightweight and battery-operated, thus, just ideal for extended fieldwork. This may also be ideal for instant monitoring and checking. Equipped with rugged components and waterproof, dustproof, chemical-resistant parts, these are ideal for outdoor testing.
One of the best things about this multi parameter colorimeteris that it is user friendly. It offers a simple, push-button program selection and a comprehensive guide that takes you through the testing procedure. Its other features are:
Complete data logging and RS232 interface capabilities. Data can be printed or downloaded conveniently, after storage or during collection.
It is compatible with Microsoft Windows and may be easily connected with the computer, making it convenient to store and transfer data. It also has a real-time clock, data memory with 100 measuring values, integrated timer, and automatic switch off-function.
These devices are waterproof, dustproof and shock proof.
It has a unique program that allows you to create around 10 custom procedures, with up to 12 data points each. This may be stored in a non-volatile instrument memory for later use.
With these exceptional features for water testing, the DR 890 becomes a much-needed device for your facility.
