The Sauermann Si-CPE320 is an evolution of the KIMO CPE 310.

For clean rooms applications, the Si-CPE320 transmitter is flush mountable to avoid disturbing the working environment. It is equipped with a highgrade stainless-steel waterproof front panel with an integrated touch screen.

Equipped with the same technologies as the Si-C320, this panelmounted version provides state-of-the-art reliability and accuracy.

In addition, measurements can be recorded and downloaded via the Sauermann Control application/software.
