The Sauermann Si-C320 is an evolution of the KIMO C 310.

For clean rooms, regulated environments and industrial VAC applications where a perfect regulation/monitoring of the air parameters is needed, our Si-C320 transmitters provide reliable measurements and allow you to achieve compliance with the strictest regulations.

The Si-C320 housing is waterproof, rugged and resistant to vaporised hydrogen peroxide (VHP). It also features a colour touch screen for comprehensive viewing and advanced control of measurement parameters.

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