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 offers a unique dew point end value prediction algorithm as a built-in technology. Based on the dew point measurement curve, our algorithm can predict the end value before actually reaching the end value. This feature enables the user to predict the dew point end value in a minimum amount of time. It helps on-site engineers to save time and to perform faster dew point audits. The dew point end value prediction is a part of the smart features.

Optional Smart Features

Dew point end value prediction is a part of the smart features. With the smart features option, users also get a 5 Megapixel camera and the snapshot function for quick measurement logging. Take a quick measurement snapshot of the current measurement, add the customer information and easily create a printed report. All can be done on the device via touchscreen input.

PDF Report Function according to ISO 8573-1

The S520 enables users to create powerful PDF Reports on-site according to the ISO 8573-1 standard. The reports are based on the recommendations stated in the ISO 8573-1. Additionally, customer related data as well as service provider details can be entered on-screen, making it even easier to perform audits and to create meaningful reports.

PDF reports can be created from any recordings on the device and are copied on the fly to a connected USB drive. The declared pressure dew point in °C is stated as the measured dew point under actual conditions. This refers to reference conditions at 20 °C/7 bar(g), as it is required by ISO 8573-1 standard. This is only possible, thanks to the integrated pressure sensor on the S520.

Two Measurement Range Options
  • The standard sensor unit has a measurement range of -100 … +20 °C Td and comes with an integrated pressure sensor.
  • The economic sensor unit offer the user a range of -50 … +50 °C Td.
