EKO's Net Pyradiometer MF-11 measures the combination of the short and long wave radiation components.
MF-11 is a unique sensor. It has the advantages of both wind-through types and wind-protection types, which have been up to now widely used in this field.
The fan is an important part of this instrument. It has three functions:
By covering the lower or the upper side of the sensor with an adaptor, the MF-11 can also be used as a pyrradiometer, which measures upward or downward radiation flux. Long wave radiation during the night has a close relation with freezing, mist, frost, minimum temperature, etc.
The sensing part of the MF-11A is the same as the one used on MF-11. However an adaptor covers the lower or upper side sensors. The MF-11A measures the upward or downward radiation flux depending on the position of the adapter.
