Plant Canopy Analyser

The Plant Canopy Analyzer (LP-80) is a precision, non-destructive instrument for measuring Leaf Area Index (LAI), canopy light interception, and Photosynthetically Active Radiation (PAR) directly in the field. It uses a quantum-sensor array to determine how much light penetrates the plant canopy, delivering accurate values for LAI, fPAR, and canopy extinction coefficient (k).

Lightweight, battery-operated, and equipped with an internal computation unit, the LP-80 enables real-time canopy analysis without sample removal—ideal for agricultural, forestry, and ecological research.

Features

• Non-destructive measurement of LAI and PAR for crops, forests, and grasslands.
• Integrated 80-element quantum sensor array (400–700 nm PAR range).
• Calculates LAI and fPAR instantly with built-in microprocessor.
• Automatic cosine correction ensures precision under varying sunlight angles
• Compact and lightweight (0.8 kg) — ideal for field deployment.
• Powered by 4 × AA batteries, ~12 h continuous use.
• USB/RS-232 connectivity for data download.
• Weather-resistant housing for rugged field conditions

Technical Parameters

Applications / Usage Areas

• Agriculture: Crop growth analysis, canopy closure, yield estimation.
• Forestry: Forest canopy density and light penetration measurement.
• Environmental Monitoring: Vegetation cover and climate model studies.
• Irrigation Management: Optimize water usage using canopy coverage data.
• Education & Research: Demonstrations of light–plant interaction dynamics.

Benefits / User Advantages

• Instant, non-destructive canopy analysis — no plant cutting.


• Precise, reliable results under diffuse or shaded conditions


• Compact and user-friendly for field deployment.

• Reduces manual data handling with onboard computation.

Best Practices & Considerations

• Take above-canopy references before and after below-canopy readings.
• Perform measurements under diffuse light (morning/evening/overcast).
• Keep sensor array clean and level.
• Avoid strong direct sunlight during readings.
• Regular calibration recommended for research-grade accuracy.
