Vaisala offers instruments for measuring both global solar radiation, net radiation and sunshine duration both in portable and fixed automatic weather stations. Easy interfacing and maintenance characterize all of these sensors.
For measuring global solar radiation, the QMS101 Pyranometer is an economical sensor. QMS101 uses a photodiode detector for creating a voltage output proportional to the incoming radiation. Due to the unique design of the diffusor.
The CMP6 is a first class pyranometer and the CMP11 is a secondary standard pyranometer as defined by World Meteorological Organization (WMO). The CMP6 and CMP11 are both suitable for the measurement of solar irradiance on a plane surface (W/m2).
The Vaisala CMA6 and CMA11 Albedometers are suitable for measuring net global radiation and/or albedo over many different types of surface. Both sensors offer the same sensitivity. They also have conical lower screens to prevent illumination of the lower glass dome at sunrise and sunset.
