This blowdown and feed boiler conductivity control system provides on/off conductivity control, chemical feed and a conductivity electrode that measures the conductivity, as well as a temperature measurement for automatic compensation for errors due to temperature fluctuations. Unit has the ability to store data and user settings which can then be transferred to a PC via a USB disk.4 Feed/auxiliary relays.
