Online Fluorescence DO Transmitter With OTA And 100～240VAC For Sewage Water

Online Fluorescence DO Transmitter With OTA And 100～240VAC For Sewage Water


The measurement methods include polarography and fluorescence. Polarography is cheap, but requires regular replacement of the diaphragm and electrolyte. Fluorescence is more expensive, but there is no need to replace the diaphragm and electrolyte and requires less maintenance.
The online dissolved oxygen analyzer with DRFN maintenance-free dissolved oxygen electrode can continuously monitor the dissolved oxygen in the water, NTC automatic temperature compensation, panel installation, suitable for use in various weather and various complex industrial environments.
