Effective and easy measurement

This probe consists of a stainless-steel head with the option of a replaceable sensor (CAP), a body with integrated electronics and a durable cable. Optical oxygen probes are distinguished by their extremely long service-life with minimum calibration requirements. The silicone membrane means that XB4-S probes also have much higher reaction-capabilities than competitive probes with Teflon elements.

The XB4-S probe is crucial from the aspect of energy savings linked to operation of the bellows and aeration of the tanks. This type of measurement ensures the optimum concentration of dissolved oxygen in the water depending on the species of fish being farmed.

  • 01 Highly-durable sheath intended for fresh water and salt water application
  • 02 Measurements taken independently of water currents around the sensor
  • 03 Robust and easily removed sensor – CAP
  • 04 Minimum operating costs
  • 05 Not sensitive to the presence of H2S or CO2 gas
