S120
S120 Oil Vapor Monitor for Compressed Air Purity Measurement
Precise measurement of oil contents in compressed air and gases, permanently or for spot checks.
Plug & Play oil vapor monitoring solution
Guided management with powerful air purity report function
Oil vapor measurement in a range of 0.001 to 5.000 mg/m3
Integrated data Logger for online monitoring and printing
Latest PID sensor technology for fast response time
Integrated dew point sensor option: -100 ... +20 °C Td
Various connection options for software and BMS
For Compressed Air, Nitrogen N₂, Carbon dioxide CO₂
The S120 Oil Vapor Sensor monitors oil vapor contents of compressed air and gases permanently or for spot checks when used as a portable unit with the S551 Portable Data Logger.
With simple installation and the outstanding performance of the S120 it makes it the ideal choice when residual oil vapor contents need to be measured. The built-in PID sensor provides highest accuracy for reliable oil vapor monitoring.
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
Guided management with powerful air purity report function
The S120 Oil Vapor Monitor features a Guided Management system that streamlines the process of generating Compressed Air Purity Reports for both oil vapor and humidity levels. These reports are fully compliant with ISO 8573-1, the international standard for air quality classification, specifically addressing the humidity and oil vapor content in compressed air systems. This ensures that users can efficiently monitor and document the purity of their compressed air, helping maintain the necessary quality standards for critical applications.
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.
