The miniDOT Clear logger measures dissolved oxygen in water and is completely self contained. It includes an optical DO sensor, a temperature sensor, batteries and a micro SD memory card. The logger collects measurements of dissolved oxygen with an accuracy of +/- 5% and temperature to +/- 0.1 degrees C. All measurements are stored internally. Data can be offloaded to a computer via the miniDOT USB cable. Temperature range is 0 to 35 degrees C with an accuracy of +/- 0.1 degrees C. Oxygen range is 0 to 150% saturation with an accuracy of +/- 10 umole/L.
PME also has an anti-fouling wiper compatible with the miniDOT logger and miniDOT Clear logger. Increase your data longevity by using the PME wiper.
The miniDOT Clear logger is constructed from a delrin plastic, which is a hard material that does not easily crack or break. All internal sensor components have been specifically designed to fit on the logger spine. The black sensor cover allows the user to easily grip and unscrew the top.
LOGGER INFORMATION & SENSOR SPECIFICATIONS
The miniDOT sensor is an optode that measures lifetime-based luminescence quenching of a thin membrane. The sensing foil contains a coating that has a variable fluorescence that depends upon oxygen concentration in the surrounding water. The sensor is able to compute oxygen concentration in mg/L and record these measurements internally. Every miniDOT Clear logger is calibrated at PME headquarters. PME calibrates each logger at 12 oxygen concentrations each at 8 temperatures for a total of 96 calibration points. The miniDOT Clear logger can sample between once every minute to once every hour. Contact PME for sample intervals outside this range.
