The HD2114.2, HD2134.2, HD2164.2 and HD2114B.2 instruments are dataloggers. They memorize up to 36,000 samples, which can be transferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. The storing interval, printing, and baud rate can be configured using the menu.
Pressure is measured using an internal differential module that compares the atmosphere with bottom of a fixed scale. With the PP471 module acting as an interface, the instrument can use all the TP704 and TP705 series Delta Ohm probes to perform the measurements. The HD2114B.0 and HD2114B.2 internal module measures the barometric pressure.
The temperature is detected using immersion, penetration, contact or air probes, with SICRAM module or direct 4-wire probes. The sensor can be a Pt100, Pt1000 or Ni1000. The temperature probes are fitted with a SICRAM module, with the factory calibration settings already being memorized inside. On being turned on the instrument automatically detects these settings.
The HD2114.2, HD2134.2, HD2164.2 and HD2114B.2 instruments can transfer via the RS232C serial port the acquired measurements to a PC or to a portable printer in real time.
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.
Instrument for the Analysis of the Indices: WBGT, PMV, PPD
HD32.3 – WBGT – PMV Index is an instrument made by Delta Ohm Srl for:
– Analysis of hot environments using WBGT index (Wet Bulb Glob Temperature: wet bulb temperature and Globe thermometer) in presence or absence of solar radiation
– Analysis of the moderate warm environments using PMV index (Predicted Mean Vote) and PPD index (Predicted Percentage of Dissatis ed)
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.
