The OxyFerm FDA is an electrochemical oxygen sensor suited for applications with high demands for hygiene, e.g. in pharmaceutical industry, in biotechnology and in foods & beverages production. It is available with 12 mm or 25 mm shaft (XL) diameter. When using Oxylyte USD electrolyte, even upside-down insertion is possible. The sensor is equipped with a FDA approved membrane for usage in hygienic processes. It can withstand steam sterilization, autoclavation and CIP cleanings.

  • Sanitary Feature: The silicone membrane seals without a gap to steel membrane body (no additional o-ring)
  • Little drift, fast response, short polarization time
  • Replacing the cathode is possible and very simple to perform
