Product Details

Alpha pH560 1/4 DIN pH/ORP Industrial Controller



Product Features


:: Αlpha pH 550 Monitor and 560 Controller allow user to select USA (4.01, 7.00 or 10.01) or NIST (4.01, 6.86 or 9.18) pH buffer standards during calibration.

:: Primary and secondary displays are available for simultaneous display of pH, ORP, Conductivity and Temperature values. Allows instantaneous viewing of measured readings and setup configurations.

:: Simply calibrate or adjust setup configuration with just a few touches of the buttons. Intelligent program in alpha pH 550 Monitor and 560 Controller prompts respective buffers for easy calibration. Similarly, push-button offset adjustment makes calibration simple in the conductivity models.

:: Compensates variance in the measured readings due to temperature fluctuations, either Automatically (with Pt 100) or Manually (Process and Calibration temperatures can be set separately).

:: Meters can be mounted on the wall or in a control panel. In addition, the IP65 rated housing allows the meter to be installed outdoors or indoors. Mounting accessories are included for both types of mounting.

:: Unique mode available in the alpha pH 550 Monitor and 560 Controller allow the meters to be operated in environments with electrical interferences. Simply configure the meter to the symmetrical mode and attach a potential matching pin.

:: Two switching contacts acting as set-point relays simplify your task of controlling various processes. Separately adjustable high and low set-point hysteresis ensure chatter-free signal at the set-points.

:: Ability to set a time-delay up to 2000 seconds eliminates unneeded control and prevents false alarms, making it ideal for industrial environments.

:: Back-lit display ensures easy reading even in the dark. UV light protection minimises adverse effect of exposure to sunlight.
