Quantum PAR Sensor – Photosynthetic Light Measurement

Quantum PAR Sensor – Photosynthetic Light Measurement

SKU: RK200-02
$650.00Price

High-precision PAR sensor for measuring light within the 400–700 nm range. Ideal for plant growth studies, greenhouse monitoring, and environmental research.

  • Product Description

    This Quantum PAR Sensor is a high-sensitivity device designed to measure photosynthetically active radiation (PAR) in the 400–700 nm wavelength range, which directly influences plant growth and productivity. Using a silicon photodetector, the sensor generates a voltage output proportional to the intensity of incident light—ideal for real-time monitoring of light energy available for photosynthesis.

    Engineered for continuous outdoor use, this sensor operates reliably in all weather conditions. Its cosine-corrected response ensures accurate readings regardless of the angle of sunlight, and each unit includes a unique sensitivity coefficient for precise measurement in μmol/m²·s.

    Compliant with WMO standards and built for harsh environments, the PAR sensor features low power consumption, a visual desiccant window, and easy installation—making it an essential tool for agriculture, greenhouses, plant research, and environmental monitoring systems.
