Photometer

Photometers measure nearly all disinfectants and the pH value based on the photometric principle. They are portable, compact and make safe, simple measurement possible.

Product description

Precise measurement results through high-quality interference filters

The photometers DT1B, DT3B and DT4B are used, among other things, as a reference method for calibrating the electrochemical sensors for chlorine, chlorine dioxide Chlorine dioxide is an exceptionally reactive gas, which is not stored due to its instability ... more in the glossary, chlorite, H2O2, bromine and ozone. They have been adapted to today's technical requirements and can be used in almost all areas of water analysis. High-quality interference filters and long-term stable LEDs are used as the light source in the high-precision optics. The entire measuring unit is maintenance-free. Precise and reproducible analysis results are achieved with minimum time and effort. The units are winning customers over with their excellent operating convenience, ergonomic design, compact dimensions and ease of use.
