Product Options


The Eutech Alpha pH 560 limit control meter simplifies the task of controlling several processes with two set point relays all in the one controller. Clear and accurate readings are ensured in electrically noisy ambients by using the symmetrical mode option, while the Automatic Temperature Compensation ensures accuracy in fluctuating temperatures. All data is displayed on the large UV light protected LCD complete with backlight.

This conroller features high/low hysteresis complete with user adjustable time delay of up to 2000 seconds resulting in minimal chattering, unnecessary down times and false alarms enhancing.

Calibration of the Alpha pH 560 is a simple process automatic recognition of US and NIST ensures this process is completed quickly and with minimal hastle to the user.
