Temperature monitoring with testo Saveris 2

The temperature monitoring system consists of at least one WiFi data logger and a Cloud access (online data store). As a component of this data logger system, the testo Saveris 2-T3 data logger with up to 2 connectable thermocouple temperature probes (TC Types K, T, J) stores all measured temperature values and transmits them directly via your WLAN to the Testo Cloud. A broad measuring range of -200 to +1350 °C is possible thanks to the connectable TC probes. You can use the alarm function to receive immediate warnings by e-mail or SMS (optional) when limit values are violated.
