Panel Mount Controllers

Single- or dual-input panel-mount pH/ORP controllers allow users to add a second sensor rather than a second controller. A simple sensor calibration process saves time, and digital inputs for each sensor-input channel prevent control based on stagnant samples or empty tanks. Control-output-limit timers prevent runaway chemical addition. Manual output activation of the W305 from Walchem Group simplifies testing of outputs during installation or allows chemical additions to be made by hand safely.
