Dissolved Oxygen Sensors from Aquametrix

Dissolved Oxygen Sensors

AquaMetrix has been making dissolved oxygen sensors for the five decades it has been in business. The 2200D analyzer and P91 sensor are Clark (membrane) based electrochemical systems and are proven in hundreds of wastewater treatment plants around the world. It is still the sensor technology of choice in Asia and much of Europe. The newer optically based probe is a new addition to the AquaMetrix product line. it's made for us by the world leader in biopharmaceutical sensors and provides both 4-20 mA analog and Modbus digital outputs.

P91 Dissolved Oxygen Probe

The sensor consist of a probe to which is fitted a cartridge that contains a precisely stretched permeable membrane, electrodes and electrolyte (p/n P91D). The inexpensive cartridge will provide continuous service for 6 to 12 months and is the easily replaced in minutes. The cartridge is supplied hermetically sealed for longer shelf life.

AM-LDO Luminesescent Dissolved Oxygen

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 and do not require flow and are less affected by fouling.
