8-sensor inline conductivity meter AEGIS ll

Water conductivity and pH meter and controller.

Applications:

  • Regulates desalination in evaporative cooling systems.
  • Controls or regulates according to the dosage amount of corrosion inhibitors, defoamers and dispersants.
  • It measures and regulates the concentration of inhibitors by means of a fluorescence sensor.
  • It measures and, if necessary, regulates the pH value and the redox voltage.
  • It regulates with dosing pumps the quantity of biocides, depending on time or measured value.

Continuous conductivity meter in the water line

AEGIS ll continuously measures and regulates conductivity and is a biocide concentration controller to keep heat exchangers and pipelines clean.

It has capacity for up to 8 sensors.
4 digital outputs 4-20 mA.
5 relés de potencia.
Recorder in micro SD memory and Wifi network connection for control through Smart technology.

Advantages

  • Biocide dosing control for 1, 7 or 28 days in real time and continuously.
  • Measures the concentration of biocides on-line.
  • Conductivity and temperature measurement and flow control with digital sensor type CTFS.
