Eutech Instruments pH 560 1/4-DIN pH/ORP Controller

Small size, economical monitor or controller with display

The pH 550 and 560 monitors are used to measure pH /ORP and temperature values in applications such as water treatment and monitoring, chemical processing, or food processing. The monitors have user-friendly features like menu-driven programs and calibrations that are easily performed with the push-button keypad. All setup and calibration parameters are retained in the nonvolatile memory to prevent data loss during power outages.


Measurements are compensated for temperature variations automatically when used with pH electrodes that have temperature elements. The monitors also offer manual temperature compensation with independent settings for calibration and process temperature. One- or two-point calibrations can be performed with USA or NIST buffer sets. All values, operational, and error messages are indicated on the large, dual-line LCD. Order 100 Pt RTD pH and ORP electrodes from pages XXXX-XXXX. Order BNC to spade lug adapter to install pH or ORP electrodes.


The pH 560 monitor has additional features including two switching contacts as set point relays. The relays have separately adjustable high and low set point hysteresis (dead bands) to prevent relay chattering. The relays feature a 0 to 2000 second time delay to prevent false alarms and unneeded control. The pH 560 also features a backlit and UV light protected display.
