Description

Controller for pH, ORP and temperature (w/ Pt100 sensor) – S503-pH/RX/T

S503-pH/RX/T

The S503 instruments are microprocessor-based digital devices, designed for panel installation. All models feature 2 relay outputs (settable as set-points or alarm thresholds), one current output completely configurable and galvanically insulated. All outputs may be temporary deactivated (e.g. during maintenance) through the ON button. Alarms and errors are shown directly on the display, and calibration and configuration data are saved into the non-volatile memory for at least 10 years.

The S503 series includes several models, for measuring the following parameters:

  • pH / ORP (redox) / Temperature
  • Conductivity
  • Indicator (model with standardized input)

All models feature a temperature input for Pt100 sensor, for temperature measurement and compensation of the pH and conductivity.
