pHotoFlex Series

Portable Photometers: Whatever the Application

With pHotoFlex and pHotoFlex Turb there is a new series of portable photometers, which have been designed especially for the use at changing locations. The pHotoFlex Series is outstanding due to it‘s unique combination of several measuring parameters : Photometry, pH and Turbidity (photoFlex Turb).

The instruments are handy, robust battery driven models equipped with accurate optics by low power consumption. They can be changed over to run with rechargeable batteries and universal power plug or alternatively upgraded with a LabStation include rechargeable battery set for a comfortable data import and export.
