Dissolved Oxygen Sensor - In-Situ Inc RDO

This uses optical fluorescence sensing technology to provide an extremely stable, precise and low maintenance dissolved oxygen sensor.

This fast-responding DO sensor does not require membrane replacement, and because it requires little maintenance, can be deployed for many months without the need for re-calibration.

It's rugged, and you can choose between a titanium or Delrin body.

It has a scratch-resistant sensor window and a teflon-coated oxygen sensor to reduce fouling and abrasion.
