The miniDOT® Logger from PME, is a fully submersible, compact and durable logger which records dissolved oxygen and temperature measurements. Suitable for use in both fresh water and saltwater environments, the MiniDOT® Logger is certified for up to 300-meter depths. Measurements can be taken at intervals from once a minute to once an hour, with data stored on the loggers internal SD card. .
The miniDOT Logger contains an oxygen-sensing optode which uses a fluorescence method to determine concentrations of dissolved oxygen in mg/L.
Power is provided by two AA lithium batteries which are user replaceable. The Logger also contains a backup coin battery.
