Product details
Purpose:
The BF5 solar radiation meter is a sensor that can directly measure the total radiation, scattered radiation, and sunshine status of the sun. It can be used in conjunction with a data collector for long-term automatic monitoring, or directly connected to a computer to view real-time readings.
characteristic:
·Measure total radiation and scattered radiation;
·Measure the duration of sunlight;
·No regular adjustment and polarity arrangement
·Measurement work can be carried out at any latitude;
·No need for moving parts, shading rings, and electric tracking devices;
·Output can choose energy units (W/m2), PAR (μ mol/m2/s), or Lux;
·Equipped with a built-in heater, it can be monitored even in rainy and snowy weather.
