This meter is an advanced portable photometer for the measurement of pH, total chlorine, and free chlorine in water.

pH is measured in the range of 6.5 to 8.5 pH and free and total chlorine are measured in water samples from 0.00 to 5.00 mg/L (ppm).


This meter offers an innovative and superior optical system that utilizes a reference detector and narrow band interference filters for extremely accurate, fast and repeatable measurements, in a short amount of time.


This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different methods, reviewing GLP data, recalling the last 50 measurements, and customizing the meter to user preferences.
