The instrument which measures the intensity of solar radiation is called:
A
Barometer
B
Energymeter
C
Solarimeter
D
Speedometer
Correct Answer: Solarimeter
The solarimeter measures routine global solar radiation on a plane or level surface. It has a thermocouple junction-sensing element. The sensing element is coated with a highly stable carbon based non organic coating, which delivers excellent spectral absorption and long-term stability characteristics. The sensing element is housed under two concentric fitting glass domes.
