Section 1.

The LI-600

The LI-600 Porometer/Fluorometer is a lightweight hand-

held instrument that takes combined stomatal con-

ductance, and Pulse Amplitude Modulation (PAM)

chlorophyll afluorescence measurements of a leaf in

seconds. It delivers precise, high-throughput stress eval-

uations over the same leaf area and can quickly survey

plants under ambient conditions.

The LI-600 has a GPS receiver that records the latitude,

longitude, and altitude for each measurement, allowing

users to track, return to, and map locations. The LI-600

includes a magnetometer/accelerometer that measures the

pitch, roll and heading of a leaf. These measurements,

along with information from the GPSreceiver, enable the

LI-600 software to calculate the angle of incidence of a leaf

for each measurement.1

The LI-600 computer software is available for both Win-

dows®and macOS®. It is used to create and upload con-

figurations to the instrument, download data from the

instrument, record live data, and create barcodes. The soft-

ware is available for download at:

licor.com/600software

1GPS and the accelerometer/magnetometer are included in

models with a serial number higher than PFA-00553.
