Sensaphone FGD-0325 Dissolved Oxygen Sensor

This is the only optical dissolved oxygen sensor that outputs directly 4-20 mA for the %-saturation and concentration (mg/l or ppm). Optical sensors offer advantages over electrochemical sensors in that they are inherently self-referencing, and require no warm-up period. These sensors do not require constant fl ow to maintain a stable reading and are less affected by fouling. Maintenance is trivial. The body is corrosion resistant and designed to stand up to the harsh environment of wastewater.
