Model LP-80 - AccuPAR


Measure Canopy PAR: The AccuPAR is a lightweight, portable PAR sensor wand that lets you measure canopy PAR interception at any location within a canopy. PAR data can be used with other climate data to estimate biomass production without destroying the crop. PAR is also important in determining other canopy processes, like radiation interception, energy conversion, momentum, gas exchange, precipitation interception, and evapotranspiration.


Calculate Leaf Area Index (LAI)

The AccuPAR also uses radiation measurements and other parameters to accurately calculate leaf area index (LAI) non-destructively in real time.

Lightweight, Self-contained

The AccuPAR weighs a little over 1 pound ( 0.5kg). The attached controller, powered by 4 AA batteries, can be used to take measurements manually or can log data unattended for short periods of time. It stores 1 MB of data (about 2000 measurements) for later download and analysis.

Includes External Sensor

The included external PAR sensor can be used to make simultaneous above- and below-canopy PAR measurements.


Extension Cable for External PAR Sensor

7.6m (25 foot) cable with locking 3-pin circular direct connections to be used with the LP80’s external PAR sensor.


External PAR Sensor

2 meter cable with connector for direct connection to the ceptometer’s external port.

Calibrated to provide an output of about 0.1 mV per μmol m-2 s-1, calibration label provided ( included with each LP-80).
