As the different systems have different functions and characteristics, they perform different tasks. Together they cover almost all needs that may arise in terms of monitoring metrics and events. For example, if you do not have access to a fixed internet connection, Celsicom can connect to NB-IoT or the mobile network. If you already have an existing WiFi network, testo Saveris Cloud may be the most economical option. If you want a system with extra high measurement security and work in your own network without depending on external services, testo Saveris 1 is the right choice. See the differences in the summary table below.
