EUTECH C301 Portable Colorimeter

EUTECH C301 Portable Colorimeter is defined as the measurement of a parameter whose concentration is proportional (directly or inversely related) to color intensity after the addition of known volume of reagent(s).

Different chemical substances absorb different and varying visual light frequencies. Since the absorbance of a substance is proportional to its concentration i.e., a more concentrated solution gives a higher absorbance reading, therefore the concentration of a known solute can be measured using a colorimeter.

Eutech’s latest range of portable waterproof colorimeters measure Chlorine (Free and Total), Cyanuric Acid, pH, Chlorine Dioxide, Bromine and Ozone. The applications include water analysis in swimming pools, spas, public utilities, industrial wastewater plants, municipal water, treated water, water conditioning systems and paper and pulp mills.
