New miniDOT Dissolved Oxygen and Temperature Logger for Water Monitoring

Precision Measurement Engineering (PME), an internationally known freshwater instrument design corporation from USA is proud to announce the release of their miniDOT, a small logger that records dissolved oxygen and temperature measurements internally for months at a time.

CEO Michael Head states, “We are very excited about the miniDOT logger because it allows users to take measurements frequently while maintaining months of service before the batteries need to be replaced.”

The miniDOT contains a dissolved oxygen sensor, which is an optode that measures lifetime-based luminescence quenching of fluorescence of a thin membrane, and a thermistor to measure temperature. Data are recorded on a 2GB internal SanDisk memory card. If the sample frequency is every 1 minute, the logger will last for 200 days. If the sample frequency is every ten minutes, the logger will last for 475 days.

Each miniDOT logger is extremely portable and easy to handle. PME will provide data visualisation software with each miniDOT. This is a Java program that displays miniDOT logger data files and computes oxygen saturation. It calculates air pressure based on elevation of the water surface above sea level.
