DO Stat

Your crop depends on consistency, and dissolved oxygen (DO) is a difficult variable to control, but the BioTherm DO Stat works with the TOOB to optimize DO levels at your set point. The DO Stat reads dissolved oxygen and temperature in your irrigation line or tank, and controls the oxygen infusion process.

Touch screen user interface displays real-time data and allows navigation to adjust settings and alarms. Dissolved Oxygen is indicated in mg/L (ppm) or in percentage of saturation. The Dissolved Oxygen readings automatically compensate for the temperature effects on the oxygen solubility and membrane permeability.
