Dew Point Monitoring According to ISO 8573-1
The plug-and-play dew point solution monitors the compressed air quality and purity according to the ISO 8573-1 standard. Meeting these requirements helps ensure fridge-dryer efficiency and reliability.
Output Signals for Great Flexibility
The dew point transmitter is available with 2-wire or 3-wire analog 4… 20 mA output signals, as well as Modbus/RTU digital interface. By offering various output signals, the sensor can be integrated seamlessly into any process.
Modbus Sensor Network with S331
The Modbus/RTU bus allows connecting several devices to a single bus line via Daisy-Chain. For example, up to 16 devices to a STUO Data Logger S331. The S331 is a powerful yet cost-efficient data logger and display solution.
Pressure Sensor and OLED Display
The S215 is offered with an integrated pressure sensor, combining a pressure and dew point sensor into a single instrument. The optional OLED display directly mounted on the sensor provides real-time values at the point of use. The display can be rotated by 340 ° to fit in any application. (Not available with 2-wire option)

SUTO Exchange Service
The SUTO 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 to the calibrated one and returned to the supplier. Find more information about our SUTO Exchange Service. Please contact us for special requests, such as custom dew point ranges or different gas types or applications.
