Designed for complete automation of water treatment system measurements (conductivity, pH and oxidation reduction potential) as well as control of chemical additives, the fully programmable CDCN13 controller also provides data logging with on-board memory for up to 999 tests. Remote communication is supported with RS232 and RS485.
The controller supports measurement accuracies of ±1% rdg in μS/(cc or ppm), ±0.1 pH, and ±10 mV for ORP, Measurements can be displayed in either English or metric units using scroll-through menus, a 16-button keypad, and 8-line LCD readout. Standard features include conductivity control, with the ability to control four additive-feed programs. (From $2,550; sensors sold separately — available now.)
