  • 2 or 4 channel versions available
  • Up to 20 days of deployment time
  • Measure ultra low oxygen
  • Export for SensorTrace Logger and CSV file
FDL Mini with sensor

Measure ultra-low oxygen concentration (<10nM) with STOX sensor

The Field DataLogger Mini offers full STOX support and makes it possible for you to study ultra-low oxygen concentrations in e.g. oxygen minimal zones and other environments containing ultra-low oxygen. The STOX microsensor differs from the standard oxygen microsensor by having automatic zero calibration.

This enables the sensor to measure extremely low oxygen concentrations <10nM.

STOX Sensor

Link to ADV’s, CTD’s and other platforms

The flexibility of our Field DataLogger Mini enables you to integrate it into your current platform. Power your Field DataLogger Mini from your CTD, ADV or other source using a 6-28 V supply, and store and synchronize your measured data on your device via our 0-5 V analog output.

FDL Mini connections

Easy setup and data export

Connect sensors, apply polarization and start measuring. After deployment, import data into SensorTrace Logger for visualization of raw and calibrated values. With SensorTrace Logger, you can export into e.g. Excel for further analysis.
