Key Features
  • Submersible up to 100 meters
  • PAR, orientation, and temperature sensors
  • Anti-fouling wiper available

Overview
The PME minPAR records temperature, tilt (3-axis acceleration), and PAR. Data is recorded on an internal SD card. The miniPAR is powered by two AA lithium batteries and can be fitted with an anti-fouling miniWIPER to protect long-term data accuracy.

Measuring Photosynthetically Active Radiation
The miniPAR is fitted with an LI-192 Underwater Quantum Sensor manufactured by LI-COR. The sensor uses a silicon photodiode and glass optical filters to achieve uniform sensitivity across the 400-700nm wavelength range. It measures PAR from all angles in one hemisphere. PAR is a key indicator for understanding nutrient loading, photosynthesis, algae blooms, and other biological, chemical, or physical processes.

Battery Powered
PME is confident that the logger can continue collecting measurements for over one year before the batteries need to be replaced at a sampling interval of one minute. The miniPAR is constructed from strong Delrin plastic that does not crack or break easily. 

Embedded Tilt Sensor
The miniPAR is unique among similar loggers in that it includes a tilt sensor that measures the device's orientation using a 3-axis accelerometer, allowing users to review tilt data alongside PAR and temperature measurements.  

PME Software Included
PME software is included with every miniPAR logger and can be found on the included SD card when the logger is connected to a computer. The software creates visual plots to read PAR measurements easily and allows the user to set the internal clock and sample rate.

Questions & Answers
Is the PME miniPAR logger compatible with the LI-COR LI-193 underwater spherical PAR sensor for unattended deployment?
No, the LI-193 is not compatible with the miniPAR logger. Typically, these sensors need to be wiped during extended deployments, making the spherical sensors impractical for those types of applications.
