Redesigned for our customers’ needs
The new SUTO Dew Point Sensors have been redesigned from ground up, integrating the latest technology and all our experience. The sensors are fully backwards compatible to existing compressed air and gas installations.
Dew Point, Pressure and Temperature
The sensor is equipped with an integrated pressure sensor, combining dew point, temperature and pressure monitoring into a single instrument.
User-friendly Outputs
The S211 Dew Point Sensor is perfectly suited to be integrated into process controls or high-level monitoring systems. Various output options are offered for a seamless integration: 4 … 20 mA 2-wire + SDI; 4 … 20 mA 3-wire + SDI; 4 … 20 mA 3-wire +; Modbus/ RTU. The S211 is easily connected to the SUTO S330/331 Displays / Data Logger as well as the SUTO Portable Data Logger S551.
Optional OLED Display
The optional OLED display directly mounted on the S211 provides real-time values on-site. The display can be easily rotated by 340 ° to adjust to any application.
Long Lasting Materials
The main body is made from high class aluminum alloy with a soft finish. The process connection material is 1.4301 (SUS 304) stainless steel, made to last forever.
The top cover is made from aluminum with the same quality as the main body.

SUTO Exchange Service
The exchange calibration service eliminates downtime and enables users to have a seamless record of their dew point measurements.
The user receives a calibrated instrument in advance with a calibration certificate and the same instrument settings. The onsite instrument is then switched against the calibrated one and returned to the supplier. More information about the SUTO Exchange Service can be found here.
Please contact us here for consultation or special requests, such as custom dew point ranges or different gas types.
