Surgical mask tester
SGN’s Surgical mask Filter Testers represent a new generation of testers designed for testing surgical masks and filter media as per ASTM F2299. The Model SMT uses a PSL aerosol that can range from 0.1 to 10 microns. It provides fast, reliable filter efficiency measurements for penetrations as low as .01% (99.99% efficiency). It can handle 1 test per 2 minutes, running complete tests with minimum operator intervention. An onboard microprocessor calculates filter penetration and resistance information over a wide range at a flow rate of 28.3 lpm. Filter test results are presented on a 7-inch HMI touch-panel display and data is saved in internal memory and can be extracted using a flash drive and printed to a computer.
Aluminum Extrusions and Structure
Aluminum Extrusion is manufactured to grade 6063 T66 to create a strong and robust extrusion with a 15-micron anodized layer to meet material handling requirements. Our profiles come from a single mill to ensure greater quality and consistency across every profile.
Volatility Tandem Differential Mobility Analyzer
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.
Aerosol Humidifier
Aerosol humidifier units are the best choice for people with high-powered central heating systems because they evaporate the water from the air in an indirect manner, creating a cooling effect without using any additional energy. This can also save your wallet money because you can use less hot water and less cool water when compared to other humidifiers. If you want to keep your home tidy, then this is a great choice as it will not leave a puddle of liquid on the floor like other humidifiers that use scented oils. We have a customized aerosol humidifier used to integrate with the SMPS unit to build an HTDMA setup.

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.
