LI-190R

LI-190R Photosynthetically Active Radiation (PAR) Sensor

Provides accurate measurements for most broad-spectrum light sources, including natural sunlight, artificial, or mixed sources, to evaluate plants' light use—in the open, in greenhouses, under plant canopies, or in growth chambers

MX2308 in a greenhouse

MX2308 Temp/RH/PAR Data Logger

Multiparameter logger captures highly precise temperature, RH & photosynthetically active radiation (PAR) measurements with a LI-COR PAR sensor and effortlessly offloads data to your device via Bluetooth

LI-200R Pyranometer

LI-200R Pyranometer

Intended for outdoor use in unobstructed natural daylight conditions, measures global solar radiation in watts per square meter (W m-2) and is compatible with most data loggers

MX2309 on a solar panel

MX2309 Temp/RH/Solar Data Logger

Logs high-precision measurements for multiple parameters—temperature, RH & Global Solar Radiation with LI-COR LI-200R Pyranometer—and downloads data effortlessly to your device with Bluetooth wireless

LI-191R

LI-191R Line Quantum PAR Sensor

Integrates below-canopy photosynthetically active radiation (PAR) measurements over 1-meter length in Photosynthetic Photon Flux Density (PPFD) units to measure non-uniform light field under canopies.

LI-210R Photometric Sensor

LI-210R Photometric Sensor

Measures light in lux or klux with the same sensitivity as the human eye to evaluate illumination in indoor environments such as offices, exhibits, and public spaces

LI-180 Spectrometer

LI-180 Spectrometer

Precision linear image sensor records intensity and composition of five color bands including near-UV and far-red, at the single nanometer level to evaluate and validate lighting strategy

LI-250A

LI-250A
Light Meter

Portable device provides a dynamic range of instant, high-resolution readings from any three BNC light sensors you connect

LI-250Q PAR Package

LI-250Q PAR Package

Takes spot measurements of photosynthetically active radiation intensity to assess adequate lighting using an LI-190R Quantum Sensor, LI-250A Light Meter, and 2003S Mounting and Leveling Fixture.

LI-1500

LI-1500 Daily Light Integral Package

Rugged data logger and quantum sensor combine to automatically capture photosynthetically active radiation measurements at specified intervals and calculate Daily Light Integral (DLI)
