The electrodes can be installed quickly and easily. Simply plug the universal BNC connector into the socket and twist it into a secured position.
With proportional control, you can fine-tune your treatment plant and minimize the use of chemicals. The proportional setting can be adjusted through the time cycle from 0 to 90 seconds and the band from 0 to 200 mV. The setpoint can be accurately adjusted through coarse and fine trimmers.
