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.
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.
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.
