The AccuPAR model LP-80 is Decagon's newest generation (replaces the AccuPAR model PAR-80) of ceptometer, designed for quick and reliable measurement of PAR and LAI in plant canopies. With the new LP-80, you get instant real-time PAR measurements as soon as you turn it on, and your LAI data is updated with each PAR measurement.

Features

• Intuitive 6-key menu-driven interface
  
• Included external PAR sensor for simultaneous above and below-canopy PAR measurement
  
• Large memory capacity
  
• Low power consumption/AA alkaline battery-powered

The AccuPAR model LP-80 is a linear PAR ceptometer consisting of an integrated probe and microcontroller. The probe is about 86.5cm long and contains 80 sensors that are sensitive to the PAR waveband. The microcontroller interprets the PAR signals coming from the probe, allowing you to read PAR. It also calculates LAI of your samples instantly with each PAR measurement you take, using the intercepted and available PAR and other variables.
