The compact transmitter /controller APM-1.. measures and controls the pH value or redox potential in aqueous solutions. It is available as panel-mounted device according to DIN/EN 61554 or as field housing.

Measured values and parameters are displayed on a high-contrast graphic display in plain text.

Easy configuration via buttons or PC with optional software provide a simple and user friendly operation.

An integrated math and logic module enables the integration of the measured values in mathematical formulas so that the measured variables can be displayed.
