DASGIP® PHPO for Monitoring of pH, DO, Redox and/or Level

pH and dissolved oxygen are two key parameters monitored and controlled in most bioprocesses in order to achieve optimum growth conditions. Depending on the application, measurement of redox potential and/or level is desired. The Eppendorf DASGIP PHPO module series provides flexible solutions for all these requirements. More information

Product Information

Eppendorf provides a range of DASGIP bioprocess monitoring modules delivering precise measurement and real-time control of pH, dissolved oxygen (DO), redox potential (ORP) and/or level/foam. Industry standard sensors can be connected. The monitoring systems enable parallel monitoring of four or eight pH sensors with temperature compensation. Additionally, up to two Pt100 temperature sensors can be connected and two 0/4-20mA/0-10V analog inputs provide external signal integration. An easy-to-use one- or two-point calibration procedure for pH, DO and temperature is integrated for use with DASware® control.
The four-channel modules PHPO (configured for pH and DO control) and PHPORD (pH, DO and ORP) each feature four optional conductivity-based level inputs. These inputs can be used for level control during continuous operation or automated antifoam addition.

Features

  • Parallel monitoring of four or eight pH sensors with temperature compensation and precise control
  • PHPO modules feature additional DO control and optional level/foam control
  • PHPORD module for four vessels features additional ORP control and optional level/foam control
  • Easy-to-use one- or two-point calibration procedure for pH, DO and temperature

Applications

  • Parallel monitoring and control of crucial process parameters in cell culture and microbiology
  • Seamless integration with DASGIP Parallel Bioreactor System
