Panel Mount Controllers offer single or dual inputs.
Series W305 pH/ORP controllers support 1 or 2 sensors in any combination of pH or ORP. Digital inputs for each sensor input channel prevent control based on stagnant samples or empty tanks, while control output limit timers prevent runaway chemical addition. Rated NEMA 4X, Ã-½ DIN controllers offer optional calibration reminder, automatic probe wash, and automatic buffer recognition. They...
