Rika RK200-02 4-20mA 0-5V Digital Output RS485 Light Quantum PAR Sensor Light Meter for Greenhouse
Rika RK200-02 4-20mA 0-5V Digital Output RS485 Light Quantum PAR Sensor Light Meter for Greenhouse
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 thesilicon-photodetector 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:
