Panel Mount Controllers

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.

Avoiding scale, corrosion and microbiological growth — all of which diminish effective heat transfer — is the focus of any water treatment approach for water-contacted process heating and cooling equipment.
