These sturdy, compact controllers withstand voltage fluctuations from 85 to 250V AC/DC! They are ideal for installation were electrical fluctuations are common, or install them in series throughout areas of differing electrical conditions.
Advanced setup mode lets you set relay values, select pH or ORP control, select manual or automatic temperature compensation, and more. It also lets you view electrode slope and offset, and previous calibration points.
The 1/8 DIN housing is ready to install in standard panels and NEMA rated boxes. Includes mounting hardware; accepts electrodes with BNC connectors and 100 Pt RTD ATC elements.
