Water analysisDIT-M, DIT-L photometers and DIT-IR interface module

DIT-L photometerThe DIT-L compact photometer quickly analyses the concen-tration of chlorine, chlorine dioxide, chlorite or ozone as well as the pH value in water treatment. High operating conveni-ence, ergonomic design, compact dimensions and safe han-dling make this unit essential for water analysis. Long-term stable reagents.
