In order to measure the pressure you use the electronic module PP471 that works as an interface between the instrument and Delta Ohm probes series TP704 and TP705. Temperature is measured by means of Pt100 with SICRAM module or direct 4 wires Pt100 probes for immersion, penetration, contact or air.
Temperature probes are equipped with SICRAM module and factory calibration data are stored inside so that when the instrument is on it soon recognizes them. The HD2124.2 is a data logger. It stores up to 32.000 samples which can be transferred into a PC connected to the instrument through the RS232C and USB 2.0 serial ports.
It is possible to configure the storage interval, the printing and the baud rate by the menu.
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 LP Silicon-PYRA 04. pyranometer measures the global solar radiation (W/ m2) by using a silicon photodiode (350nm-1100nm). The special geometry and the diffuser allow to have a pyranometer field of view of 180 degrees according to cosine law.
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.
