Dissolved Oxygen

There are optical dissolved oxygen sensors with 4-20mA and RS485 outputs, used in aquaculture, fish farming, lakes, rivers and water treatment, including O2 control in activated sludge tanks, and measurement and control systems with relay outputs and temperature display.

For field work and remote monitoring, multiparameter probes measure oxygen together with other parameters, and a modular system monitors and controls several research or aquaculture tanks.
