Part #: pg-k



Where large fish are present, especially in high concentrations like aquaculture, there is always the risk that sharp fins may damage the membrane of dissolved oxygen sensors.  The pHishGard prevents this by creating a barrier around the electrode while allowing adequate water flow for accurate measurements.

Durable and chemical resistant Delrin® is used to withstand both the physical stress of large fish running into the guard, along with any environmental stress from the sun and water.  Delrin® also does not release potentially harmful compounds into water, ensuring the long-term health of the environment.
