FSDO 5310 Online Polarographic Dissolved Oxygen MeasurementInstrument Detailed Introduction
The Fesks Online Polarographic Dissolved Oxygen Analyzer FSDO 5310 adopts a new microcomputer chip and is an analytical device designed for online analysis of dissolved oxygen in water quality. It features high intelligence, stable readings, and an easy-to-operate intelligent controller. Depending on monitoring parameter requirements, it can be paired with the KSDO 310/320 polarographic electrode to measure ppm/ppb-level dissolved oxygen and temperature in both high-temperature and normal-temperature water quality.
