Description
The testo Saveris 2 wireless WiFi data logger system is a flexible, easy-to-use, yet reliable solution for monitoring temperature and humidity in warehouses, cold storage rooms, and production facilities. The system consists of at least one WiFi data logger and a license for access to the Testo Cloud storage (online data storage). As a component of the system, the testo Saveris 2-T1 temperature logger with an internal NTC sensor measures and stores temperature parameters, and transmits the measured values via the WiFi network to the Testo Cloud storage. The measurement interval can be freely configured from 5 s to 24 h. You can also use the alarm notification function, sent via e-mail or optionally via SMS when established limits are violated.
Installation of WiFi data loggers, data readout, and analysis
The testo Saveris 2-T1 WiFi data loggers can be easily installed and commissioned by a user without special technical skills. Several license options are available for access to the Testo Cloud, which implements functions for viewing and analyzing measured values. You can use these functions remotely, via an Internet-connected smartphone, tablet, or PC. Thanks to API access (optional), you can export measurement data to your own system.
Current measured values, violations of established limits, and remaining battery life are displayed on the logger’s screen. The service life of standard AA batteries is 24 months. Batteries can be replaced by the user. The logger’s internal memory is 10,000 values, and the housing has an IP 65 protection rating. The testo Saveris 2-T1 WiFi loggers comply with EN 12830.
