TSI 3073 Portable Test Aerosol Generator

Description of TSI 3073

The Portable Test Aerosol Generator 3073 is a truly portable high-end test aerosol generator. Polydisperse test aerosols are generated by atomizing various oils or salt solutions where the mode of the produced particle size distribution is typically between 0.15 and 0.3 µm. Monodisperse particles such as PSL can be generated as well from liquid suspensions. The innovative new flow control via nozzle pressure sensor and proportional valve achieves highly stable low particle production rates. Selecting the same set point, yields the same concentrations again and again.

In the lab the model 3073 is ideally suited for calibration setups where low but stable aerosol concentrations are needed. Particle measurement instruments can typically be connected without additional dilution. Due to the new nozzle operating mode also high concentrations can be produced stable over long periods (VDI 3491-2).

For field use the model 3073 can be equipped with a user-supplied battery pack. This transforms the model 3073 into a completely stand-alone unit. The significantly reduced power consumption allows run times up to several hours depending on pack capacity and operating conditions. The model 3073 also features and external control interface that enables remote control which is very helpful in duct measurements.
