    Sensor

    The same controller can actuate equipment based on pH or oxidation reduction potential (ORP). Using two SPDT (single pole, double throw) relays, these controllers can turn pumps, valves, and other equipment on or off when a reading reaches the actuation point. They also send output signals to a PLC or other receiving device to record data and control equipment. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. These controllers are often used for water treatment, electroplating, and chemical processing.
    They require a pH or ORP sensor (sold separately).
    LED Display—Controllers with an LED display are more visible in low-light conditions than those with an LCD display.
    Washdown Environments—Controllers for washdown environments are rated IP65 for protection against low-pressure washdowns and dust.
