Widely used in liquid test

Place the Ubibot GS2 and its EC and PH probes in the environment where it will be used, such as a hydroponic farm, aquarium, wastewater pond, or laboratory, and you can view the real-time data in the monitoring center. Then you can download the daily or monthly report for regular analysis. It makes unattended monitoring much easier but more accurate.
