Dissolved oxygen and temperature data logger

SDOT enables data acquisition and recording of dissolved oxygen concentration and saturation measurements and temperature measurements.
SDOT uses an Anderaa dissolved oxygen sensor.

Several versions of the SDOT are available, depending on sensor and depth rating, for use in coastal areas or deep waters (6000m)

Easy to use:

  • Light and compact
  • Remote setup and fast wireless data transfer with a Data Pencil and a computer (Winmemo software)
