miniDOT® Clear Logger - DO & Temperature Monitor
A completely submersible instrument that logs dissolved oxygen and temperature. Ideal for hatcheries, aqua farms and aquatic product transportation.
The miniDOT® Clear Logger is a water quality monitoring device that records measurements in real-time displayed through an internal LCD screen, granting quick access to water quality data. The oxygen sensor is an optode that measures dissolved oxygen concentration in water through a fluorescence method. These features allow users to view vital water quality data just by looking at the device to save valuable time if dissolved oxygen or temperature levels began to rapidly shift.

miniDOT® Clear Logger
The miniDOT® Clear Logger is a completely submersible instrument that logs dissolved oxygen and temperature measurements and has an internal LCD screen, which displays real-time measurements. The oxygen sensor is an optode that measures dissolved oxygen concentration in water through a fluorescence method. Data are recorded to an internal SD card. Operation of the miniDOT® Clear Logger such as setting the time and sample interval can be accomplished via the USB cable.
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. More about the miniWIPER.
Product Design
The miniDOT® Clear Logger is constructed from a durable plastic to ensure the longevity of the device as it lowers the risk of product damages. 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.

Technology
The miniDOT® Clear 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.
