DDS 560/C Dynamic Dilution System
Touchscreen-controlled dynamic aerosol dilution system with automatic readjustment, variable 0.5–3.0 L/min sample flow and RS-232 integration for automated aerosol measurements.
Model Overview
| Model | Configuration | Primary use | Selection note |
|---|---|---|---|
| DDS 560/C | 5–370, flow-dependent; 0.5–3.0 L/min | Touchscreen-controlled dynamic aerosol dilution system with automatic readjustment, variable 0 | Select DDS 560/C for automated, remotely monitored dilution with automatic setpoint control and variable instrument sample flow. |
Key Features
Wide adjustable dilution range
Provides a freely adjustable dilution factor over approximately one decade, with the available range dependent on sample flow.
Automatic setpoint readjustment
The control system readjusts the dilution setting to maintain the selected value as operating conditions change.
Variable passive sample flow
Compatible with aerosol analytical instruments using sample flow rates between 0.5 and 3.0 L/min.
Touchscreen operation
Local touchscreen menus support setup, operation and instrument-status review.
Remote communication
RS-232 communication supports remote control and parameter monitoring in automated measurement systems.
Fast operating setup
Published setup time is no more than 10 seconds under the specified operating conditions.
