The DR300 Pocket Colorimeter measures the amount of light transmitted through a liquid sample. Analyte in the sample reacts with reagents, creating colored compounds. The intensity of the color created is proportional to the concentration of the analyte in the sample.

What does a Hach colorimeter measure?

The DR300 Pocket Colorimeter measures the amount of light transmitted through a liquid sample. Analyte in the sample reacts with reagents, creating colored compounds. The intensity of the color created is proportional to the concentration of the analyte in the sample.

What is a pocket colorimeter used for?

Use the chlorine Pocket Colorimeter II with the USEPA approved Free and Total Chlorine methods in Drinking Water and Total Chlorine method in wastewater analyses. The Pocket II is a fast way to test chlorine that is compact, easy to use, and accurate.

How do you calibrate a pocket colorimeter?

Each Pocket Colorimeter II Instrument is pre-programmed for one of more than 35 parameters. Many are based on EPA-approved methods. No manual calibration is ever required. Simply zero the instrument with a blank, insert the reacted sample, and read the result.

Can we use spectrophotometer instead of colorimeter?

The spectrophotometer works well for color formulation, measurement of metamerism, and variable illuminant/observer conditions. The colorimeter works well for routine comparisons of similar colors and adjustment of small color differences under constant conditions.

How much is spectrophotometer?

Amaze Instruments The price of Digital Spectrophotometer products is between ₹80,000 – ₹125,000 per Piece during Apr ’21 – Mar ’22.

How do you calibrate a Hach DR900?

To set a standard adjust on the DR900 Multiparameter Portable Colorimeter (Product # 9385100), first select the program needed to adjust. Once the program is set, run a standard of known concentration for the specific test. When the results are on the display, select Options –> Advanced Options –> Standard Adjust.

How do you use free chlorine strips?

Just dip the strip, wait until color development occurs, and compare the color of the reacted pad to the chart printed on the bottle. *This product has not been evaluated to test for chlorine and chloramines in medical applications in the United States. A 12% surcharge may be added to the product price.

Why spectrophotometer is preferred over colorimeter?

One of the advantages of spectrophotometer over colorimeter is that it may offer much more precision and advanced features and provide more accurate data; making it useful for a broad range of applications in R&D, color formulation, and quality control but it tends to be a more expensive option.
