Thousands of engineers and ecologists already depend on the ATMOS 14 for straightforward measurements. Whether you’re using the EM60G to look at plant emergence, leaf area index, or fractional interception, there isn’t an easier way to benchmark your data. The ATMOS 14 is a versatile, low-maintenance, and fast sensor designed to make taking temp/RH measurements […]
