The S120 oil vapor monitor for compressed air quality provides continuous or spot monitoring of oil vapor content in compressed air and gases. When used as a portable device together with the S551 data logger, it allows spot checks. Thanks to its simple installation and outstanding performance, the S120 is the ideal choice for measuring residual oil vapor content. The built‑in photoionization detector (PID) ensures the highest accuracy for reliable monitoring.
Monitoring oil vapor content is a mandatory requirement in many industries to prevent product contamination and risks to human health. The S120 sensor makes monitoring of oil vapor in the range of 0.001 to 5.000 mg/m³ accessible and reliable. Simply connect your compressed air system via the sampling hose and quick‑connect fitting.
An optional integrated 5″ touch screen with data logger function is available, facilitating data viewing and storage. Various output signals – 4…20 mA (isolated), Modbus/RTU (RS485), Modbus/TCP (Ethernet), and USB – allow easy connection of the S120 oil vapor monitor to SUTO iTEC data loggers and displays or to central building management systems.
The integrated automatic calibration compensates temperature and humidity drifts in the supplied air, ensuring accurate, reliable, and long‑term stable measurement results.
To ensure compressed air quality, in addition to oil vapor monitoring, dew point measurement is a key parameter. Therefore, we offer an optional integrated dew point sensor (measuring range –100 … +20 °C Td), allowing both parameters to be measured in one compact device with an excellent price‑to‑performance ratio.
The S120 sensor features a guided measurement reporting system that simplifies the creation of compressed air purity reports for oil vapor and moisture content. These reports fully comply with ISO 8573‑1 (the international standard for air quality classification) with respect to moisture and oil vapor content. This enables users to efficiently monitor and document compressed air purity, maintaining the required standards for critical applications.
The SUTO exchangeable calibration service eliminates downtime and ensures continuous recording of oil vapor monitoring results.
The S120 is designed for efficient measurement of residual oil content in a compressed air system. Simple plug‑and‑play installation and outstanding performance make it the ideal choice when oil vapor needs to be measured and monitored. The sensor is used in various industries and applications, including:
The Guided Measurement feature in the S120 simplifies the process of monitoring and reporting oil vapor levels. This intuitive feature guides users step‑by‑step through the measurement process, allowing them to generate and export detailed compressed air purity reports as PDF files without the need for external software. The reports comply with ISO 8573‑1 requirements, ensuring that your compressed air system meets the required purity levels. With the S120, maintaining air quality standards is efficient, accurate, and straightforward.
