TSI 3073 Portable Test Aerosol Generator


The Model 3073 is a high end test aerosol generator for low and high concentration polydisperse droplet aerosols. It generates submicron aerosols from oils, and from salt or PSL solutions. The innovative new flow control reduces power consumption and achieves highly stable low particle production rates, ideal for calibration of particle sizing instruments. Its compact and lightweight design coupled with battery operation make it a perfect fit for use in field test applications.
