The Palintest Photometer 7100 is a direct-reading, waterproof photometer for determining key water quality parameters for drinking water, wastewater and process water samples.

Designed for both portable and laboratory use, the Photometer 7100 should always be used with genuine Palintest reagents for optimal performance.

The fundamental operating technique applied to the Photometer 7100 is based on the principles of optical absorbance and scattering of visible light.

Optical absorbance techniques are based on the use of Palintest (spectro)photometric reagents, creating visible colours with specific analytes upon reaction. The intensity of colour produced is measured with the Photometer 7100 and the data compared to the stored calibration data to deliver the final result.

Optical scattering techniques produce small particles to scatter the source beam, the amount of scatter providing a result for the concentration of parameter under test.
