The Aerosol Sensor Test System AFC 135 combines the features of the successfully established test systems for filter media and elements (AFC 131/AFC 132).
Additionally the range of application ius extended to the development, testing and calibration of sensors for number or mass-related determination of the particle loading of aerosols (PMx-and PNx- sensors). The wide field of application is made possible on the one hand by the flexible sensor integration (active and passive sensors) and on the other hand by the realisation of a wide volume flow range. On customer request, the test system can be equipped with 2 measuring sections to cover volume flow rates between 0,8 ... 40 m³/h and 40 ... 450 m³/h.
Benefits
- providing stable, defined aerosols at variable volume flow rates
- generation of solid and/or droplet aerosols
- adaption to customer-specific requirements possible
- integration of Topas equipment and external devices
Applications
- calibration and quality assurance of PM sensors during production
- testing of PMx and PNx fine dust sensors during development
- studies on the ageing behaviour of sensors
- aerosol-technical fundamental resear
Accessories
- customer-specific devices and sensors is possible on request
- various sample holders of the AFC 135 for sensors, sampling probes, flat media and other components
