ATMOS 14 Gen 2 comparison

ATMOS 14 Gen 2 is now compatible with a fan-aspirated radiation shield (Apogee TS-100), and temperature sensor accuracy now meets WMO recommendations. An improved physical design and calibration process yields higher performance and includes a field replaceable sensor daughter card for easy maintenance. An individual calibration certificate is now available for each sensor. See comparison table below.
