Kipp & Zonen receives a lot of questions about whether a particular data logger is suitable for use with our instruments. These are mainly from the solar energy sector, where users are less familiar with the signal output than in meteorology and climate research. Let me share my experiences on dataloggers to you.
I will concentrate on our CMP series pyranometers for measuring global and diffuse horizontal irradiance (GHI and DHI) and plane of array (POA) irradiance. However, similar considerations apply to the CHP1 pyrheliometer for measuring direct normal irradiance (DNI).
