Ensure Your Compressed Air Quality
Oil free compressed air is not an easy task to be achieved. Monitoring oil vapor content is a must in many industries and applications to avoid contamination in products and risk to health of humans. The S120 makes monitoring oil vapor in a range of 0.001 to 5.000 mg/m3 affordable and reliable. Just connect your compressed air system through sampling hose and quick-connector.
Display Option and Various Output Signals
The optional integrated 5” touch screen display with data logger function help to easily view and store data.
Various output signals, such as 4 … 20 mA (isolated); Modbus/RTU (RS485); Modbus/TCP (Ethernet) and USB, can be used to easily connect the S120 Oil Vapor Monitor to SUTO Data Loggers and Displays or central building management systems.
Integrated Automatic Calibration
The integrated automatic calibration compensates temperature and humidity drifts in the supplied air resulting in accurate, reliable and stable measurement results over a long period of time.
Optional integrated Dew Point Sensor
To ensure compressed air quality and purity, further from oil vapor monitoring, dew point measurement is an essential key parameter. Therefore, we offer an optional integrated Dew Point Sensor (-100 … +20 °C Td) to measure both parameters in one compact device with an excellent price performance ratio
SUTO Exchange Service
The exchange calibration service eliminates downtime and enables users to have a seamless record of their oil vapor monitoring. Please find more information here.
