Dissolved Carbon Dioxide (CO2) Sensor (Water – Soil) hall effect making it easy to integrateThe measurement of dissolved carbon dioxide in water is one of the most important parameters in the field of aquaculture and in industry. So, this Carbon Dioxide (CO2) sensor probe allows the measurement of dissolved carbon dioxide directly in the water and soil. It can measure the Carbon Dioxide (CO2) concentration with high accuracy with large measuring range up to 5000 ppm. The CO2 probe has an analog both RS485 and TTL output for connection to
