For a successful and accurate measurement we offer highly precise and easy to use photometers: either spectrophotometers photoLab® 7100 VIS / 7600 UV-VIS, maintenance free, robust and highly precise filter photometers photoLab® S6/S12 or the portable LED colorimeters pHotoFlex® STD / pH / Turb. Together with the multiple options for test kits, they are forming a photometric analytical system. Particularly for AQA demands, the barcoded and lot certificated test kits are recommended. Additionally checking tools like multi-parameter standards CombiCheck, instrument check with PhotoCheck and many more are ensuring plausibility and accuracy of reported measuring results with a great ease of use. 

Besides the pure measurement tasks, the correct sampling, sample preparation and meter handling with zeroing and  regular checks are mandatory.

In the Photometry Compendium you'll find videos and a big collection of useful information, tips and tricks as well as application reports. To be up-to-date on Xylem analytics and WTW products and their application fields just sign up for our Newsletter.
