Introduction to photometers

What is a photometer and how does it work ?

A domestic photometer, generally, is an optical instrument that measures light intensity after it has passed through a sample solution which contains a specific reagent. This reagent (either tablets, powders or strips) is added to a predetermined quantity of your solution sample and as the light passes through it, the optical properties are interpreted by the photometer to give you a measurement of your chosen parameter. The types of parameters available vary between different photometer models with the more expensive devices offering in excess of 50 parameters. Some models will also offer Bluetooth connectivity so your results can be sent to your smartphone, some offer GPS data to show where the test was undertaken whilst the less expensive models offer a very simple ‘dip & read’ action to test for the most important water safety parameters.

What are the benefits of a photometer over test strips ?

There are many ... photometers take out the guess work by using digital accuracy (no comparing colour charts), easier clean up (no drops), instant results, excellent record keeping options (some will keep records on your smartphone) and economically priced reagents. Photometers offer great features for cost-effective onsite water testing for the water professional and home users alike.
