The price is affordable, and it is easy to use, but it is not able to transmit data to the control system for online monitoring to do some water quality analysis. The professional instrument has high accuracy and can send data to the control system, but the price is expensive for ordinary people. To this end, we have launched an analog TDS sensor kit that is compatible with Arduino, plug, and play, easy to use.
