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 temperature probe TP32MTT.03 is equipped with seven Pt100 1/3 DIN sensors for the measurement of temperature at depth: +5 cm, 0, ‐5 cm, ‐10 cm, ‐20 cm, ‐50 cm, ‐1 m with respect to the soil level, according to the indications of the World Meteoro‐ logical Organization (WMO). The probe TP32MTT.03.1 is equipped with six Pt100 1/3 DIN sensors for the measure‐ ment of temperature at depth: +5 cm, 0, ‐5 cm, ‐10 cm, ‐20 cm, ‐50 cm with respect to the soil level.
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.
