Your present location:HomeproductsSolar & Light Detector - RK200-02 PAR Sensor
  • Product Name: RK200-02 PAR Sensor

The RK200-02 PAR Sensor is mainly used for measuring solar radiation within 400~700nm wavelength. It is easy installation and can work continuously in all weathers. When there is sunlight, voltage output proportional to incident light intensity will be generated by the silicon-photo detector in the sensor. Its sensitivity is proportional to the cosine of incident light direct angle. Each product is with one sensitivity coefficient respectively. It can directly output radiation value in unit of μ*mol/m2*s.

FEATURES

  * Metal construction
  * Harsh environment workable
  * High sensitivity
  * No power supply measurement
  * Compact size for easy use

APPLICATIONS

  * Agrometeorological research
  * Crop growth monitoring
  * Ecological research
  * Environment surveillance
  * Greenhouse control
