Compact Photometer
The photometer PF‑12Plus is a device tailored for mobile water analysis. Equipped with more than 100 pre-programmed methods, it is the ideal companion for all fields of water and wastewater analysis.
With its especially positioned 860 nm LED the PF‑12Plus enables nephelometric turbidity measurements (NTU) in the range of 1–1000 NTU. The unique NTU-Check controls turbidity in parallel to every measurement. NANOCOLOR tube tests and VISOCOLOR ECO tests can be evaluated with the PF‑12Plus.
