TDA-2G Portable Photometer		The TDA-2G portable photometer is the smallest, lightest unit available anywhere with more advanced features and superior performance compared to existing photometers.
TDA-4B Aerosol Generator		The TDA-4B is the latest design in rugged, lightweight Laskin nozzle generators from ATI. The TDA-4B is a small, compact aerosol generator which requires only a supply of clean, compressed air to create polydispersed sub-micron aerosol. It has a 6 nozzle design, and @20 psig, when diluted with 810 cfm of air, produces 100 µg/l.
TDA-4Blite Aerosol Generator		The TDA-4Blite was specifically designed for use in biosafety cabinets. Its small size and low cost make it the ideal generator for testing biosafety cabinets or low flow cleanroom systems. It has a 3 Laskin nozzle design, and at 20 psig diluted with 405 cfm of air, the aerosol concentration is 100 µg/l.
TDA-5B Aerosol Generator		The TDA-5B Aerosol Generator has been designed to provide operator convenience and improved performance. The TDA-5B is ideal for certifying or testing HEPA filters or installations with air flows from 500 to 65,000 cfm. It requires an inert gas source and 120/240 volts @ 750 watts electrical service.
TDA-6C Aerosol Generator		The new TDA-6C Aerosol Generator has been designed to produce a poly-dispersed sub-micron aerosol using either 2 or 6 Laskin nozzle jets.  The unit is suitable for use in systems from 50 to 2,000 cfm.
PSL Jet Atomizer		The PSL Jet Atomizer is a versatile, low-cost, rugged unit capable of testing cleanroom systems up to 100,000 cfm with Polystyrene Latex (PSL) spheres. It is ideal for certifying cleanrooms in microelectronic facilities or where traditional oil-based aerosols are prohibited.
TDA-99M Protective Mask Leakage Tester		The portable TDA-99M Protective Mask Leakage Tester is a revolutionary piece of equipment designed to test the serviceability of any protective mask worldwide. The TDA-99M can be completely set up in minutes, and is completely self-contained in a rugged, shippable case. Utilizing solid-state electronic circuitry with simple menu-driven touch pad controls, the TDA-99M enables efficient data capture and analysis of mask testing results.
TDA-99B Protective Mask Test System		The TDA-99B Protective Mask Test System is a revolutionary piece of equipment designed to test the serviceability of any protective mask worldwide. The TDA-99B can be easily set up in minutes utilizing solid-state electronic circuitry with simple touch screen controls.  The TDA-99B enables efficient data capture and analysis of mask testing results with unsurpassed flexibility.
TDA-100P Automatic Filter Tester		The TDA-100P Automatic Filter Tester utilizes state-of-the-art technology and microprocessor control. The new design features a user friendly interface to minimize setup and operator training. All functions and operation parameters of the machine can be programmed using just 4 function keys and the menus are shown on an easy-to-read, alphanumeric vacuum fluorescent (VF) display.
TDA-110P Automatic Filter Tester		The TDA-110P Automatic Filter Tester is a state-of-the-art system for testing medium-flow air filters up to 400 cubic feet per minute.  It is part of the ATI family of Automatic Filter Testers which includes the low-flow TDA-100 series and the high-flow TDA-120 series testers.  The TDA-110P is ideal for testing automotive and airline cabin-air filters, vacuum filters, industrial or commercial ventilation filters, compressed air filters, collective protection military filters, and many other types of medium-flow air filters.
TDA-D10 -D100 Aerosol Diluters		The ATI Aerosol Diluters were developed to fill a specific need in the HEPA filter testing industry. The diluter enhances the effectiveness of optical particle counters by diluting the upstream concentration of an aerosol to prevent saturation of the particle counter. The diluter has been designed to minimize pressure drop and aerosol loss as a function of particle size.
