PHOTOMETERS-ITS-SERIES-CHART.pdfPhotometry / spectrophotometry is an assay based on measurement of the absorbance of a specific wavelength of light while passing through a fixed path-length through a cuvette of liquid test sample. The absorbance is compared with a blank and standards with graded amounts of the target compound. In colorimetry, The emitted light is of a specific visible wavelength.

About our photometers
Now there is an alternative to powder pillows, powder packets, tablets, glass ampoules, and liquid systems: Reagent Strips! Each strip has one or more test pads containing reagents for colorimetric detection of ions in water samples. By dipping a strip into a cell, the exact amount of reagent is released into the water causing a reaction. The reaction inside the water sample is measured by light inside the photometer giving the user fast and exact results.
Only 3 simple & quick steps:
Tests for water quality include:
