The DP 510 provides precise dew point measurement in compressed air and technical gas systems and enables reliable dryer diagnostics even at extremely low dew point values (down to −80 °Ctd).
The fast response time enables rapid detection of dryer performance changes and immediate insight into process conditions during service inspections.
The 3.5-inch graphical touchscreen display provides intuitive operation, while measurement curves are displayed graphically, allowing dryer performance to be evaluated at a glance from the start of the measurement.
The integrated 16 GB data logger allows storage of up to 100 million measurements. Logging intervals are freely configurable, and each measurement can be stored with a custom comment (e.g. measurement location).
Measurement data can be easily transferred to a computer using a USB flash drive. In addition, the 'Photo' function allows the current screen to be saved as an image file without additional software.
The DP 510 automatically calculates important moisture parameters such as g/m³, mg/m³, ppm V/V, g/kg, % RH, and atmospheric pressure dew point, simplifying result interpretation in the field.
The key advantage of the DP 510 is the second freely configurable input for third-party sensors. Supported signal types include 0–1/10 V, (0) 4–20 mA, pulse signals, and Modbus/RS-485. The DP 510 can also display values measured by external sensors.
Quick installation with a measuring chamber and quick coupling, combined with a dry storage container for sensor protection, ensures safe and efficient operation. The DP 510 is designed as an all-in-one solution for service teams, with everything organized in a transport case.

Fast verification of refrigeration, membrane, and desiccant dryer performance through accurate on-site dew point measurements.

A reliable tool for routine maintenance of compressed air and technical gas systems, enabling rapid detection of moisture-related issues and prevention of equipment failures.

The portable dew point meter with integrated data logging is ideal for field measurements, system commissioning, process validation, and temporary diagnostic inspections.
