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. **Si-CPE320:** Optional wireless communication module **Si-CPE320-W:** Integrated wireless communication module [ Technical Data sheet ](https://www.kimo-instruments.com/sites/default/files/files/DS_Si-CPE320_EN_24-01-25.pdf) [ User manual ](https://www.kimo-instruments.com/sites/default/files/files/UM_Si-CPE320_EN_11-07-25.pdf) [ Simplified manual ](https://www.kimo-instruments.com/sites/default/files/files/QSG_Si-CPE320_24-01-25_12.pdf) 1 x input for external probe 3 x analogue outputs Graphic touch display IP 66, VHP resistant (Vaporized hydrogen peroxide) Outputs diagnostic Possibility to edit the channel names Product info #### Measure details -
