LI-200R Pyranometer

The LI-200R Pyranometer is meant to be used outdoors under unobstructed natural daylight conditions. It measures global solar radiation—the combination of direct and diffuse solar radiation—in the 400 to 1100 nm range.

The LI-190R Quantum Sensor

The LI-190R measures Photosynthetically Active Radiation (PAR, in µmol of photons m-2 s-1). It provides accurate measurements—in the open, in greenhouses, under plant canopies, or in growth chambers—for most broad-spectrum light sources.

LI-192 Underwater Quantum Sensor

The LI-192 Underwater Quantum Sensor measures PAR from all angles in one hemisphere. The LI-192 works in air or underwater at depths up to 560 meters. The measurements are cosine corrected and typically expressed as Photosynthetic Photon Flux Density (PPFD).

The LI-193 Spherical Quantum Sensor

The LI-193 Spherical Quantum Sensor measures PAR in air or underwater from all directions at depths up to 350 meters. This sensor is useful for studies of phytoplankton, which uses radiation from all directions.

LI-210R Photometric Sensor

The LI-210R Photometric Sensor measures light with the same sensitivity as a typical human eye. The photometric sensor is ideal for evaluating illumination in work areas, exhibits, interior lighting, and in public spaces. Measurement units are lux or klux.

LI-250A Light Meter

The LI‑250A is a portable meter that displays the output from any LI‑COR® light sensor that has a cable terminated with a BNC connector. It shows instantaneous values or 15-second averages of values from a sensor.

LI-1500 Light Sensor Logger

The LI-1500 Light Sensor Logger provides a direct digital readout and data logging from up to three LI-COR sensors at the same time. Log manually or set up one-time, daily, or continual logging routines. The menu-driven interface is easy to use. View real-time light measurements, GPS data, and other variables on the eight-line display screen.

LI-180 Spectrometer

Plant growth and reproduction are driven by Photosynthetically-Active Radiation (PAR), which occurs at wavelengths between 400 and 700 nanometers.

The precision linear image sensor of the LI-180 captures intensity and composition of five wavebands (380-780 nm) at the single-nanometer levels with a single click.

Optimise the composition of your supplemental lighting and track your spectrometer data over time for long-term validation of your lights and lighting strategy.
