The HD3901 leaf wetness sensor detects the presence of condensation on its sensitive surface and has been designed to reproduce in an extremely accurate way the thermodynamic behaviour of a leaf. The leaf wetness degree is a basic information in the agricultural and floriculture fields to determine the most appropriate phytosanitary treatment to prevent mould and fungal infections in general that can affect the plants and crops in the presence
of condensation on the leaves.
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.
HD2030 is a portable vibration analyzer performing spectral and statistical analysis on four channels simultaneously. The instrument measures all parameters required by current regulations concerning workers protection from vibration related risks and is able to measure vibrations transmitted to both hand-arm and whole body.
HD9408.3B is a barometric transmitter that uses a piezoresistive high accuracy and temperature-compensated sensor. It allows to measure the atmospheric pressure in the range from 500…1200 hPa, providing extreme accuracy and time stability, with excellent repeatability, low hysteresis, and excellent temperature behavior.
