CGR 4 Manual

4.16. Environmental

The CGR series are intended for outdoor use under all expected weather conditions. The radiometers

comply with IP 67 and their solid mechanical construction is suitable to be used under all environmental

conditions within the speciﬁed ranges.

4.17. Uncertainty

The measurement uncertainty can be described as the maximum expected hourly or daily uncertainty

with respect to the ‘absolute truth’. The conﬁdence level is 95%, which means that 95% of the

datapoints lie within the given uncertainty interval representing the absolute value. Kipp & Zonen

empirically determine uncertainty ﬁgures based on many years of ﬁeld measurements.
