New miniDOT Dissolved Oxygen and Temperature Logger for Water Monitoring
PME has developed a new optical dissolved oxygen and temperature logger for use in a variety of liquid environments. A unique design allows each logger to collect data for many months.
Vista, CA, July 15, 2011 --(PR.com)-- Precision Measurement Engineering, Inc. (PME), an internationally known freshwater instrument design corporation 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. The miniDOT oxygen logger can be programmed to make measurements at 1 minute intervals to 1 hour intervals.
This oxygen logger collects measurements of dissolved oxygen with an accuracy of +/- 5% and temperature to +/- 0.1 degrees C. The miniDOT oxygen logger is self contained and able to function within a variety of liquid environments. Data are stored on an internal SD card and are offloaded to a computer via a USB card reader.
Each miniDOT logger is extremely portable and easy to handle. PME will provide data visualization 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.
The miniDOT logger can be used in a variety of monitoring applications. The fluorescence technology allows this logger to effectively and accurately collect dissolved oxygen measurements in many different liquid sources. Applications include lakes, rivers, estuaries, oceans, water treatment outfalls, water column profiling, aquaculture and waste water.
