Why Choose the DP 400 Mobile?
Integrated Pressure Measurement up to 16 bar
The integrated pressure sensor allows simultaneous measurement of pressure and dew point as well as calculation of pressure-dependent parameters such as g/kg, ppm v/v, and atmospheric dew point.
Portable Design for Field Use
The DP 400 Mobile is specifically designed for field work – a rugged service case, integrated rechargeable battery, and simple connection system ensure fast deployment anywhere.
Sensor Protection and Fast Response Time
The integrated measuring chamber with drying cartridge protects the dew point sensor during transport and ensures rapid stabilization at the start of measurements.
Measurement of All Important Moisture Parameters
In addition to dew point, the system measures and calculates temperature, relative humidity (%RH), absolute moisture (mg/m³, g/m³), and other key parameters.
Optional Data Logger
With the optional integrated data logger, up to 100 million measurements can be stored with freely adjustable logging intervals and start/stop times.
Expandable with Additional Sensors
Up to two additional external sensors (flow, pressure, dew point, 4–20 mA, Modbus RTU) can be connected, allowing adaptation to a wide range of applications.
Intuitive Touchscreen Operation
The 3.5-inch touchscreen provides easy access to all measured values, graphical trend displays, and intuitive menu navigation.
