HD2127.1 and HD2127.2 are instruments fitted with two inputs. They measure temperature by means of immersion, penetration, contact or air probes. Their sensor can be Pt100 with 3 or 4 wires, Pt1000 with 2 wires. They have centesimal resolution in the range ± 199.99°C, decimal in the rest of the range.
The HD2013 is a reliable and sturdy tipping bucket rain gauge, built entirely from corrosion resistant materials in order to guarantee its durability. So as to ensure accurate measurement even with low temperature climatic conditions or during and after precipitations of snow, a version with heating which is automatically activated around +4 °C has been developed so that snow deposits and ice formations are prevented.
The Sunshine Duration sensor LP SD18 measures sunshine status and duration. The WMO (World Meteorological Organization) defines the sunshine duration as the time during which the direct solar radiation exceeds the level of 120 W/m2.
The HDWME microphone unit is suitable for long term outdoor monitoring, even in a fixed unattended location. The unit is adequately protected from rain and wind and the heated preamplifier provides stability of acoustic parameters over time and allows to make measurements over a wide range of environmental conditions.
