AM-LDO Luminesescent Dissolved Oxygen DatasheetSource: Aquametrix
Aquametrix has been selling polarographic dissolved oxygen analyzers for over three decades. We are now pleased to be able to offer an optical dissolved oxygen sensor that outputs directly a 4-20 or Modbus signal. Optical DO sensors offer advantages over electrochemical DO sensors in that they are inherently self-referencing, require no warm-up period, do not require flow and are less affected by fouling.
Maintenance is trivial. The sensor cap lasts for an industry leading 3 years or longer and is inexpensive to replace. The body is corrosion resistant and designed to stand up to the harsh environment of wastewater.
