3 Application
The S520 is a dew point meter that is designed to monitor the dew
point in the industrial application within the permissible operating
parameters. These parameters can be found in the Technical data
chapter on page 9.
The S520 can measure and display the following values for compressed
air or gas:
•Dew point, default unit: °C Td
•Humidity, default unit: °C Td
•Temperature, default unit: °C
•Pressure, default unit: bar (g)
The S520 dew point meter is mainly used in compressed air systems in
industrial environments. It is not developed to be used in e plosive
areas. For the use in e plosive areas please contact the manufacturer.
4 Features

•Two sensor solutions available:
◦Sensor A: Standard sensor unit with a range of
-100 … +20°C Td
◦Sensor B: Economic sensor unit with a range of
-50 … +50°C Td
•Smart dew point prediction
•Integrated pressure sensor
•Modern colour touch screen interface
•Data logger, USB interface, and Bluetooth connection to a portable
printer
•Measuring/parking chamber, designed for fast sensor response
•Application software included
•Integrated camera for more elegant reports
•ISO8573-1 Class indication
