The CTgrow industrial pH (potential of Hydrogen) sensor probe is a critical component of the HYD-2/4 Pro+ hydroponic sensing units, as it measures the acidity or alkalinity of the nutrient solution. Maintaining the proper pH level is crucial for plant growth and health, as it affects the availability of nutrients and the ability of the plant to absorb them.

The pH sensor works by measuring the concentration of hydrogen ions in the solution, which determines the pH level. The sensor consists of a special electrode that is sensitive to changes in the concentration of hydrogen ions. When the electrode comes into contact with the nutrient solution, it generates a small electrical signal that is sent to the HYD-2/4 Pro+ unit for processing and monitoring.

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