The VisiFerm DO is the first optical oxygen sensor with integrated opto-electronics, having the full functionality of a measuring device with self diagnostics. It is steam sterilizable, autoclavable and CIP compatible. The VisiFerm requires less maintenance than a classical oxygen sensor as it does not have a mechanically sensitive membrane or a corrosive electrolyte. Available with the ECS mode (Clark cell simulation).

  • No fragile membrane - with a solid sensor cap
  • No polarization time required
  • Instantly stable values, low drift, quick response
  • Convenient pre-calibration in the laboratory, because data is stored in the sensor head
