The distinctive feature of this data logger is its ability to acquire data from instrumentation and autonomously transmit them to a server via an integrated GPRS modem and data connection. The server receives the data, stores and processes them, and makes them available through a secure, password-protected web portal accessible via user ID and password. Access to the configuration panel is performed through a standard web browser and requires no software installation on the client side. The web portal provides the following functions: • Reading of selected variables • Graphical trend visualization of measurements • Data export in multiple formats • Alarm management • Alarm event logging
