4TS dSeal L100™ is a data logger that monitors the integrity of a closed space such as a delivery package.
The L100 data logger is equipped with a light sensor that provides users with a message if a designated package has been opened somewhere along the way between the sender and the receiver. The device executes a time stamp in its memory every time the package is opened. The device also hosts a large data memory, a rechargeable long-life battery and an internal clock, which is calibrated to the UTC.
Data logging frequency and minimum/maximum limit values for the light sensor can be set with any PC equipped with a miniSD memory card reader and 4TS dMonitor Lite™ PC software. The software is also used to download and view the data in the device's memory.

PC Application for Device Management
4TS dMonitor Lite™ PC software is an easy-to-use application for making settings and for extracting recorded data from 4TS dSeal data loggers.
This comprehensive software is included with every 4TS dSeal device. The data gathered by the device sensors is recorded on a miniSD memory card. In this way, users can simply insert the memory card into a memory card reader and view the data on a computer. The data view displays the device information, a summary of the logging session, data graphs with time stamps and a list of alert events.
