The Testo Saveris 2-H1 Wi-Fi data logger system is a simple, versatile, and secure temperature and humidity measurement and monitoring solution. At least one Wi-Fi data logger and a Testo Cloud license are required for the system to work (online data storage).
With its internal temperature and humidity probes, the Testo Saveris 2-H1 Wi-Fi temperature and humidity logger measures and accurately records temperature and humidity readings over extended periods of time. Measurements can be accessed from any internet-connected device, such as a tablet, PC, or smartphone, using the Testo Cloud service.
Installation, readout, and analysis of Wi-Fi data loggers
You can easily install a Testo Saveris 2-H2 Wi-Fi data recorder. Choose the right Testo Cloud license for the needs of your firm, connect via your WLAN network, then log in to Testo Cloud for logger configuration and measuring collection. Settings of logger, system, alarm and output can be set fast. Relax now, because Saveris 2 is at work and is warning you whether there is a limit or problem.
The current measurement data, alarm conditions, and remaining battery life are all displayed on the logger itself. Standard batteries (AA) have a 24-month lifespan and can be replaced as needed. The Wi-Fi data logger's internal data storage may store up to 10,000 measurement values per channel/measurement type.
