Leaf area measurements provide insights into light availability and plant physiological responses that impact productivity, growth, and nutrient dynamics. Designed for the field—and to lead the field of plant physiology research, our flexible, intuitive tools help you precisely measure leaf area and photosynthetically active radiation (PAR) of plant canopies with precision to assess plant health and canopy conditions.
Industry-leading indirect Leaf Area Index (LAI) measurement tool which accurately aids in determining growth rates and productivity in crop or natural systems without disturbing the canopy, with flexibility that outperforms Ceptometry and Hemispherical Photography methods
Learn more about your plant's canopy using this lightweight instrument, ideal for rapidly measuring the area, length, average width, and maximum width of attached leaves without harming the plant.
Rapidly takes leaf-level information for an understanding of whole canopies. Measures high-throughput stomatal conductance and chlorophyll a fluorescence to track plant physiological stress/performance throughout the growth cycle.
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.
Rugged outdoor design attaches to up to three sensors with BNC connectors to log photosynthetically active radiation (PAR), global solar radiation, and spectral light.
Monitors photosynthetically active radiation (PAR), temperature, and humidity with high precision in one logger that includes a LI-COR 190R PAR sensor and effortless Bluetooth data offload. Ideal for capturing environmental conditions—from agricultural operations to academic research.
Research-grade, multiparameter microclimate monitoring solution with effortless Bluetooth data offload that continuously measures global solar radiation, temperature, and humidity. Ideal for agricultural, environmental research, ecology, and energy applications.
A valuable tool for understanding canopy structure and light dissipation across canopy types, this portable meter displays output from any LI-COR light sensor (LI-190R, LI-191R, LI-192, LI-193, LI-200R, or LI-210R) with a BNC connector, automatically selecting a sensitivity range to optimize accuracy to provide a dynamic range for high-resolution measurements, even in low-light conditions.
