Process Dissolved Oxygen Sensor

For aquaculture and wastewater, our process dissolved oxygen probes are design for long term deployment. They feature reliable and fast responding galvanic technology with mV or 4-20 mA outputs. In addition, customization is available to tailor DO sensors for specific applications or packaging requirements.

The DO6400 & 7400 series dissolved oxygen sensors feature a large capacity electrolyte holder, positive fit, easy to replace membrane and dependable galvanic cell technology for long term deployment. The body design ensures a good grip when wet. Ideal for aquaculture and wastewater monitoring applications, these sensors require minimal maintenance. PTFE or High-Density Polyethylene (HDPE) membranes are available. 2 Replacement membranes, installation tool and electrolyte are included. Additonal maintennace parts are in convenient kits (see ordering information). Sensors with mV output as well as built-in 4-20mA output in 0-100% and 0-200% saturation range are available.
