Optical Luminescence Quenching Dissolved Oxygen Probe

DX 530 – Economic field sensor
Ideal for freshwater aquaculture, river monitoring, well analysis, and wastewater control. Paired with devices like the PRO D01, it offers a highly competitive and reliable measurement solution.

DX 532 – Robust sensor with depth measurement
Built for harsh environments such as wastewater and seawater aquaculture. Its integrated hydrostatic depth measurement and strong water protection enable easy recording of oxygen saturation profiles and identification of thermoclines down to ~30 m.

DX 535 – Compact 12 mm lab-style sensor
Suited for near-surface waters and wastewater up to 1 m depth, and ideal for laboratory use. Its 12 mm design and non-consuming optical principle ensure maximum precision, e.g., for BOD measurements.
