A spectrophotometer is an instrument that measures how much light is absorbed by a water sample as light passes through it.
After adding chemical reagents to a water sample, those reagents react with analyte(s) to form a color complex. Spectrophotometers then use internal calibrations to equate that color to the concentration of the parameter being measured.
Spectrophotometry is one of the most common and useful methods of quantitative analysis of many water parameters in various industrial and municipal applications.
Choose Hach portable or benchtop laboratory spectrophotometers (VIS or UV-VIS) in combination with Hach reagents for accuracy and optimal water quality assurance.
Portable, handheld spectrophotometers allow you to analyze water samples in the field.
If you primarily operate in a mobile environment, Hach portable spectrophotometers offer quality and accuracy to your measurements in a rugged, compact, user-friendly package.
Lab spectrophotometers measure light absorbance across the visible ranges of the electromagnetic spectrum. Ideal for high-volume water analysis needs.
Our user-friendly benchtop spectrophotometers are pre-programmed with over 250 methods optimized for laboratory water analysis.
UV-VIS lab spectrophotometers measure light absorbance across the ultraviolet and visible ranges of the electromagnetic spectrum.
Our UV-VIS instruments have guided procedures and include pre-programmed testing methods and our integrated quality assurance software – Claros, The Water Intelligence System.
Find instructor-led training sessions and digital learning courses to help you get a clear understanding of your spectrophotometer equipment and expand your expertise in water quality analysis.
