-Overview-
The MDS-1T Ions sensor, adopting the ion-selective electrode (ISE) method, enables real-time, continuous, and accurate measurement of various key ion parameters in water, including Ammonia nitrogen (NH4-N), nitrate nitrogen (NO3-N), fluoride ion (F), chloride ion (Cl), calcium ion (Ca), etc.
The sensor requires no chemical reagents or complicated sample pretreatment. The digital sensor can be directly immersed in the water sample for measurement, can use a controller to perform data acquisition, display, alarm control, 4–20 mA output, and Modbus communication. Featuring cost-effectiveness, reliability, easy operation, and long maintenance intervals, it is widely applied in process control and water quality management in wastewater treatment plants, environmental monitoring, and other fields.
