WISG traceable calibration
More accurate and lower cost than competing ‘budget’ sensors, The MS-20 Pyrgeometer (MTI.AWS.EK.20) is) designed to capture downward atmospheric longwave radiation from 4.5μm to 42μm, and can measure the net radiation between the earth and the atmosphere by using two MS-20 upward and downward facing, with a specially coated silicon window to block solar radiation wavelengths below 4.5μm.
