RK200-02 Type B Photosynthetic Active Radiation (PAR) Sensor
PRODUCT DESCRIPTION
The RK200-02 Type B is a versatile, high-performance sensor engineered to deliver precise, real-time measurements of two critical light parameters: photosynthetically active radiation (PAR) and total radiant irradiance (W/m²). Designed for professionals in agriculture, solar energy, ecology, and environmental research, it bridges the gap between specialized scientific needs and practical field deployment—offering unmatched versatility across diverse applications.
At its core, the Type B expands beyond traditional PAR sensors by combining dual measurement capabilities: it captures light in the 350–1100 nm range (encompassing ultraviolet, visible, and near-infrared wavelengths), making it uniquely suited for studies requiring broader spectral analysis, such as plant photobiology, solar panel efficiency assessment, or ecosystem energy balance research. Unlike single-function sensors, its integrated design eliminates the need for multiple devices, simplifying setup and reducing costs in multi-parameter monitoring systems.
