Choose the right electrode for your requirements from the HANNA Dissolved Oxygen range.
Our Dissolved Oxygen probes are supplied with a DIN connector unless otherwise stated. Select the right cable length for your needs (1m, 4m, 10m, 20m). Screw-cap membranes make for easy replacement in a few seconds! The edge® DO electrode comes with a built-in temperature sensor. Calibration is also fast and simple. Sensors are Polarographic or Galvanic. Galvanic probes do not need conditioning before use and are suitable for high bio-load environments such as fish farming.
