Temperature only is measured by immersion, penetration or contact probes. The sensor can be a Pt100 or Pt1000.
When the humidity/temperature combined probe is connected, the instrument calculates and displays the absolute humidity, the dew point, the partial vapour pressure, and the comfort indices. The probes are fitted with an automatic detection module, with the factory calibration data already stored inside.
The HD2101.2 is a datalogger. It stores up to 38,000 samples which can be transferred from the instrument connected to a PC via the multi-standard RS232C serial port and USB 2.0. The storing interval, printing, and baud rate can be configured using the menu.
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.
HD 9408T BARO, HD 9408TR BARO and HD 9908T BARO are analog output electronic barometers. They use a piezoresistive sensor element which gives extremely accurate and stable measurement of the atmospheric pressure and assures excellent repeatability, low hysteresis and very good temperature stability.
2 axes ultrasonic Anemometers series HD 52.3D…. The instruments of the series HD52.3D… are 2 axes ultrasonic static anemometers for measuring:
– Wind speed and direction, U-V Cartesian components of wind speed
– Relative Humidity and Temperature (optional, code ‘17’)
– Diffuse Solar Radiation (optional, code ‘P’)
– Barometric pressure (optional, code ‘4’)
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.
