Colorimeters

Introduction to Colorimeters

A colorimeter is an analytical instrument used to determine the concentration of substances and physicochemical parameters in water samples based on optical absorbance principles. The device effectively serves environmental monitoring, extensive water analysis, and routine testing in stationary laboratories or mobile monitoring stations.

When selecting a colorimeter, users should consider specific analytical goals to choose between standard 6-wavelength colorimetric versions or models integrated with turbidity measurement and electrochemical pH/ORP measurement functions. A compact handheld design is also an important criterion for frequent on-site field surveys. Hoa Viet currently distributes colorimeters from WTW (Germany) and is ready to receive requests and provide configuration advice tailored to each laboratory's intended use.

Which brand of colorimeters does Hoa Viet supply?

Currently, Hoa Viet supplies colorimeters from WTW (Germany), including portable models for water quality testing.

How do the WTW pHotoFlex colorimeter versions differ?

The pHotoFlex STD series features 6 wavelengths dedicated to standard colorimetry, the pHotoFlex Turb integrates turbidity measurement, while the pHotoFlex pH combines photometric measurement with electrochemical pH/ORP testing.

Can portable colorimeters be used in stationary laboratories?

The device is flexibly designed to meet both field testing requirements and routine, in-depth analysis in stationary laboratories.

How to select the right colorimeter model?

Users should consider the parameters to be evaluated and whether turbidity or pH/ORP measurements are required on the same device. Please send your requirements to Hoa Viet for precise equipment advice.
