The LI-600N
The LI-600N Porometer/Fluorometer is a lightweight handheld instrument that takes combined stomatal conductance and Pulse Amplitude Modulation (PAM) chlorophyll a fluorescence measurements of a needle or leaf in seconds. It delivers precise, high-throughput stress evaluations over the same needle or leaf area and can quickly survey many conifer needles, narrow leaves, and grass blades under ambient conditions.
The LI-600N 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-600N includes a magnetometer/accelerometer that measures the pitch, roll and heading of a needle/leaf.
The LI-600N computer software is available for both Windows® and macOS®. It is used to create and upload configurations to the instrument, download data from the instrument, record live data, and create barcodes. The software is available for download at licor.com/support/LI-600N/software.html
Components
The LI-600N components are as shown below.
- Chamber. Surrounds the needle/leaf gasket, the site of the active measurement.
- Clamp. Closes onto the needle/leaf.
- Fluorometer. Takes PAM chlorophyll a fluorescence measurements.
- Quantum sensor. Measures ambient light level.
- Accelerometer / Magnetometer (internal). Measures pitch, roll, and heading.
- Display. Shows measurement workflow, instrument settings, and variables data.
- Navigation arrows. Moves up, down, right, and left through options and screens.
- Enter button. Powers on the instrument, logs measurements, and selects options.
- Handle. Encloses the rechargeable battery.
- Micro-USB port. Connects the instrument to the computer or universal charging adapter via micro-USB cable.
