to be specified at the time of placing the order
Accuracy +2.5…-2.5% in the interval 0…100 mm/h
(version with 0.2 mm @ 50 mm/h nominal resolution)
+1.5…-1.5% in the interval 0…100 mm/h
(version with 0.5 mm @ 50 mm/h nominal resolution)
The error refers to the calculation of the amount of rain using
the resolution stated in the rain gauge label.
If the amount of rain is calculated using the correction curve as
a function of the rainfall rate (fig. 1 and 2), the error is typically
less than ± 2% in the interval 0…200 mm/h.
If the HD2013-DB data logger is used, the measurement can be
automatically corrected according to the graphs in fig. 1 and 2.
Maximum rainfall rate 600 mm/h (version with 0.2 mm nominal resolution)
1000 mm/h (version with 0.5 mm nominal resolution)
