Plant Canopy Analyzer (YT-GC10)

 Function

Widely used in agricultural production and scientific research, this instrument is used for automatic or manual measurement and recording of photosynthetic active radiation (PAR) within a width of 400-700n meters for investigating canopy light resources and studying the relationship between crop growth and development, yield and quality, and light energy utilization. The measurement value is in micromoles per square meter per second（ μ Mols-1m-2).

 Characteristics

The entire set is composed of two parts: a data collector and a probe rod. The probe rod includes 18 independent sensors that can simultaneously measure the PAR values of the upper and lower canopy layers. Probe length: 50 cm

PAR measurement range: 0-2700 μ Mol m-2s-1, resolution: 1 μ Mol m-2s-1, data storage capacity: 1MB, automatic collection interval: optional 1-60 minutes

 Main technical parameters:
