The 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 your acquisition system.  

You simply need to immerse the CO2 probe directly into the environment you want to monitor, whether it's a fish farm pond, a lake, the open sea, in a bioreactor, or a manufacturing process. The sensor then provides a continuous measurement of the partial pressure of dissolved CO2 in water.
