The ion content in water has a great influence on aquatic organisms and the ecological environment. Conditions where some ions are too high or too low can lead to aquatic life death or habitat destruction. By monitoring changes in water quality ions, timely measures can be taken to protect aquatic organisms and the ecological environment. The online ion controller can add a variety of ion composite sensors. Based on the ion selective electrode method, it can detect chloride ions, sodium ions, potassium ions, calcium ions, fluorine ions and other ions. In addition, the controller also has the function of temperature detection and compensation for the measured water sample. The ion controller is configured with 2 SPST relays by default, 2 channels of 4-20mA current output and an optional RS485 interface. The controller power supply is powered by a wide voltage to avoid interference caused by voltage instability. We currently offer ion controllers in two sizes, the small size is suitable for panel installation, and the large size can be wall-mounted or pipe-mounted. universal ion controller, online ion meter, water ion controller Suzhou Delfino Environmental Technology Co., Ltd. , https://www.daruifuno.com
