HD2178.1 and HD2178.2 are portable instruments with a large LCD display. These instruments measure temperature by means of immersion, penetration, contact or air probes with Pt100 or thermocouple probes.
You can connect a 3 or 4 wires Pt100 sensor or a 2 wires Pt1000 sensor to B input, a K, J, T, N, E type thermocouple to input A. Probes to B input, a 8-poles DIN45326 connector, are equipped with an automatic detection module, with the factory calibration settings already being memorized inside. A input is equipped with a miniature female polarized connector for thermocouple probes.
The instrument HD2178.2 is a data logger; it stores up to 80.000 samples that can be transferred to a PC when connected to the instrument through a RS232C serial port or a USB 2.0 port. It is possible to configure the storage interval, the printing and the baud rate by the menu.
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.
