Systems for collecting environmental data

It´s possible to equip libraries, museums and archives with a computerized system that allows the recording of the main environmental micro data: Relative Humidity and Temperature.

The system consists of a variable number of measurement stations that detect the physical parameters at predetermined intervals by the head of the Institute.

The data is stored in a memory for each station that can be of 3,700 measurements.

The measurement ranges can be set up from 1 second up to several hours.

Data can be downloaded to a laptop via an interface and then be handled by specialized software.
It is also possible to adopt a convenient system for data collection consisting of a portable memory that lets you download data from 25 measuring stations and then download them to the central computer. Data from each station may be made in the form of printouts and / or graphic and they may be printed or saved on a multimedia support.
