New PAR Measurement Logger Launched
Published on by Water Network Research, Official research team of The Water Network in Technology
Precision Measurement Engineering has launched the new miniPAR Logger that logs photosynthetically active radiation (PAR), water temperature and tilt measurements.

The completely submersible logger measures the amount of diffused sunlight through water, which can be beneficial for understanding nutrient loading, photosynthesis and algal blooms in natural waters up to 100 meters deep.
The miniPAR sensor is a Li-Cor Underwater Quantum Sensor, which measures PAR from all angles in one hemisphere. The logger also records tilt, which will help the user understand the orientation of the logger and alerts the user as to whether or not the sensor was rotated in any particular direction. PAR measurement accuracy is dependent upon the stability of the sensor pointed towards the water surface.
PME also offers a miniWIPER for the PAR logger so that long-term deployments are made possible. Algae growth on the sensor can drastically change the accuracy of the PAR measurements, but with continuous wiping, the user can be confident in PAR monitoring over extended periods of time. PME also supplies various software for viewing and retrieving the miniPAR Logger data.
PME has also been working with several academic institutions to bring the miniPAR to fruition to meet demand for this segment of the market.
