Dissolved Oxygen Optical Sensor AM-ODO / AM-ODO2

 AquaMetrix Dissolved Oxygen Optical AM-ODO / AM-ODO2 has been selling polarographic dissolved oxygen analyzers for over four decades. We are pleased to offer the only optical dissolved oxygen sensor with dual 4-20mA outputs (% saturation and concentration in ppm’s or mg/l). The choice is up to the user to operate the sensor as a single output (%sat or ppm) or dual outputs (%sat and ppm) at the same time. Other parameters, such as temperature or pressure configurations are available per request.

The output of the ODO or the ODO2 sensors can connect directly to a PLC or to the AquaMetrix 2300 controller. Please see the main differences in the attached data sheets.

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 membrane lasts for approximately 2 years and is inexpensive to replace. The body is corrosion resistant and designed to stand up to the harsh environment. No sensor on the market packs as much into one small package at such an affordable price.
