The S520 Portable Dew Point Meter offers users a single hand-held unit to easily perform on-site measurements in compressed air and gas systems. With its state-of-the-art dew point technology, the S520 provides dew point monitoring at the point-of-use. The first steps toward maintaining high standard compressed air quality and purity conditions.
Unique Triple-Sensor System
With the combination of a QCM and a Polymer sensor in a single unit, the user can measure the dew point in a range from -100 °C Td up to +20 °C Td. without having any drawbacks in terms of accuracy. The integrated pressure sensor allows converting the measured value into any humidity value needed, for example ppm(v) or atmospheric dew point.
Dew Point Value Prediction
The S520 Portable Dew Point Meter includes an innovative dew point end value prediction algorithm, which anticipates the final value based on the measurement curve, allowing users to predict it quickly. This feature saves time for on-site engineers, enabling faster dew point audits, and is part of the device’s smart features.
Optional Smart Features
Dew point end value prediction is one of the smart features. Users can also access a 5-megapixel camera and snapshot function for rapid measurement logging, all controllable via touchscreen input for added convenience.
PDF Report Function according to ISO 8573-1
The S520 allows users to generate ISO 8573-1 standard-compliant PDF reports on-site, with options to input customer and service provider details for comprehensive audits. Reports can be created from any device recordings and swiftly copied to a connected USB drive. The device’s integrated pressure sensor ensures accurate measurements under actual conditions, meeting ISO standards.
