The CTgrow DO (Dissolved Oxygen) sensor probe is an essential component of the HYD-2/4 Pro+ hydroponic sensing unit, as it measures the amount of oxygen dissolved in the nutrient solution. Oxygen is critical for plant respiration and the uptake of nutrients, and maintaining proper oxygen levels is essential for healthy plant growth.

The dissolved oxygen sensor works by using a special electrode that reacts with oxygen in the solution. As oxygen diffuses through a semi-permeable membrane on the electrode, it generates a small electrical current that is measured by the HYD-4 Pro+ unit. This provides hydroponic growers with accurate and reliable information about the oxygen levels in the nutrient solution, allowing them to adjust aeration and circulation systems as needed.

CTgrow's dissolved oxygen sensor probe is designed to work seamlessly with the HYD-2/4 Pro+ unit, ensuring that it is properly calibrated and compatible. This allows hydroponic growers to obtain precise and accurate measurements of dissolved oxygen levels, helping them to maintain optimal growing conditions for their plants.

CTgrow's DO ezo circuits are needed to ensure that the DO sensor is properly calibrated and compatible with the HYD-2/4 Pro+ units, providing accurate and reliable DO measurement data. With this information, hydroponic growers can adjust the nutrient solution's concentration of salts and minerals for optimal plant growth and health.
