Precision Measurement Engineering, Inc. (PME) products

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 miniWIPER is a self-contained, completely submersible, wiping device that can be used with a variety of sensors. It can be programmed to wipe at various intervals, and is powered from two AA Lithium batteries. A small brush rotates over the sensor in order to perform a complete wipe of the sensor surface, and then rests away from the sensor to allow for accurate and continuous monitoring. The wiper is used as an anti-fouling device and may reduce the growth of various organisms on the sensor.

The Cyclops-7 Logger connects to one Turner Designs Cyclops-7 sensor at a time. PME offers a fixed sensor version as well as an interchangeable sensor version. The logger records measurements internally at a variety of possible sample rates. Data are offloaded from the logger to a computer via a standard USB cable. The logger is completely self contained and waterproof. Internal power allows the logger to operate for roughly 28,000 samples.
