Description:

Net total radiation sensor (net total radiation meter), based on the principle of thermoelectric effect (thermopile), measures the net difference between the total wave radiation projected downward from the sky and the total wave radiation projected upward from the earth's surface. Net total radiation meter, composed of 2 short-wave radiation meters and 2 long-wave radiation meters. Short-wave radiation meter consists of quartz cover, sensing element, meter body and other components. Long-wave radiation meter consists of silicon arc filter cover, sensing element, platinum resistor, meter body and other components. Each radiation meter can output each data separately, and can measure short-wave radiation, long-wave radiation, total wave radiation, net total radiation, short-wave reflectivity, and long-wave reflectivity.
