Gestecno’s single and dual channel datalogger powers the sensor and saves the data. It is powered by a long term lithium internal battery and has a "non-volatile" memory to ensure data retention with no power temporary absence.
It is supplied with a cable to connect it to a laptop and with a software, through which it is possible to program acquisition times and set a whole range of useful configuration parameters. The stored data are saved to your PC directly into files that are readable with Excel and other well-known spreadsheets.
Exceptional autonomy due to very low power consumption (with a one-hour measurement range, battery life is over 2 years), large storage capacity, compact and robust performance and high quality of components, make this datalogger a unique tool for surveying data for long periods and/or in unattended or not easily accessible locations.
