Fast, powerful and reliable — the Volatility Tandem Differential Mobility Analyzer provides the most comprehensive testing solutions available today. Its unique multiplexing methodology allows improved test precision, allowing the user to improve test reliability and reduce costs.
Differential Mobility Analyzer
The Differential Mobility Analyzer is a high-precision, rugged and fast direction finder that provides accurate readings for the measurement of linear and rotary movements.
Hygroscopicity Tandem Differential Mobility Analyzer (HTDMA)
The hygroscopicity tandem differential mobility analyzer (HTDMA) is a scientific instrument used to measure the hygroscopic growth of aerosol particles. It consists of two differential mobility analyzers (DMAs) connected in series, with humidification of the chamber between them. In the first DMA, aerosol particles are classified according to their size, based on their mobility in an electric field. The classified particles then enter the humidification chamber, where they are exposed to controlled levels of humidity. The second DMA then classifies the particles based on their increased size due to hygroscopic growth.
Particulate Matter (PM1, PM2.5, PM10, TSP)
DustTrak_Family-5001187_USA-web Only the TSI DustTrak™ DRX Aerosol Monitors can simultaneously measure both mass and size fraction. The DustTrak DRX handheld monitor is a multi-channel, battery-operated, data-logging, light-scattering laser photometer that gives you real-time aerosol mass readings. It uses a sheath air system that isolates the aerosol in the optics chamber to keep the optics clean for improved reliability and low maintenance. It is suitable for clean office settings as well as harsh industrial workplaces, construction and environmental sites, and other outdoor applications. The DustTrak DRX handheld monitor measures aerosol contaminants such as dust, smoke, fumes and mists.
