The HygroLog NT and associated HW4 software comply with FDA 21 CFR part 11 regarding electronic record keeping. The HygroLog NT can be networked to the purpose of monitoring and capturing data from several locations to a PC. On-site data logging by the HygroLog NT, combined with the capability of automatically downloading log files to the PC, provides protection against loss of data in the event of a power outage or network failure. Using a docking station, up to 7 probes and two external contacts can be connected to a single HygroLog NT.
