Automated Filter Tester 8150
The Automated Filter Tester 8150 is designed for 100% quality assurance testing of P100, FFP3, P3 and similar respiratory filters and cartridges directly in the production line. The 8150 is a highly compact automated filter tester with a very small footprint that easily fits into any existing and new production lines. Using many of the same technologies, it provides matching results to the Automated Filter Tester 8130A while being optimized for high-volume throughput and around-the-clock remote operation with repeatable and accurate test results. Its highly flexible configuration and robust Modbus communication capabilities go beyond current standard performance in the market while minimizing downtime.
Automated Filter Tester 8130A
The Automated Filter Tester Model 8130A continues to be the best solution for testing particulate respirator filters, disposable filtering face pieces, and a wide assortment of filter media. TSI filter testers have been used in quality control and manufacturing by leading filter and filter media manufacturers and reference test institutes around the world for more than 20 years due to their proven durability and reliability, which is valued in demanding manufacturing environments and QA/QC laboratories.

Automated Filter Tester 3160
Automated Filter Tester Model 3160 determines the pressure drop and fractional efficiency at different particle sizes (<15 to 800+ nm) in order to obtain the most penetrating particle size (MPPS) of HEPA and ULPA filters and filter media. It is designed to comply with the test requirements of EN 1822 parts 3 and 5. Filter tests are performed automatically following user-specific test parameters and up to 99.999999% fractional filter efficiencies.

Casella Guardian2 Site Boundary Monitor
The Guardian2 Site Boundary Monitor is designed to help you remain compliant with site emission levels, using remote monitoring and reporting of noise, dust and vibration levels.
Remote Particle Counters
Their small size, flexible power options and wireless capabilities allow installation where space is limited. Worry-free monitoring with best-in-class data buffering reduces risk of data loss during network outages. Only the AeroTrak™+ Remote Particle Counters are backed by an industry exclusive 5 year laser warranty. All TSI AeroTrak+ Remote Particles Counters and AeroTrak Remote Particle Counters comply with ISO 21501-4. TSI Remote Particle Counters are available in a variety of: Flow rates Particle sizes Analog output options Wireless enabled VHP resistant remote particle counter models available
BioTrak Real-Time Viable Particle Counter
The only accepted method to replace active and passive air sampling in Grade A. This biofluorescent particle counter provides real-time counts of total and viable particles in pharmaceutical manufacturing environments to reduce aseptic interventions, improve root-cause investigations, and increase process knowledge.

Portable Particle Counters
Engineered for you, they provide real-time cleanroom particle counting in an easy-to-use, reliable instrument that's ready for measurement. Built-in global regulatory guidance and international standards, such as ISO 14644-1:2015, ISO 21501-4:2018, EU GMP Annex 1 (2008 and 2022), and China GMP, make cleanroom classification testing simple. All TSI Portable Particle Counters include: Highly intuitive touch-screen display for straightforward sampling and setup Easy-to-use interface guides users through the classification process TrakPro™ Lite Secure Software, providing: Easy generation of certification or monitoring reports Fast, simple method to upload sampling configurations to particle counter Enhanced data integrity capabilities to meet regulatory requirements Additional capabilities include: Full compliance to ISO 21501-4 Operation as a standalone instrument or in conjunction with a facility monitoring system like TSI FMS Software Models with high flow rates allow for rapid testing of large volumes Built-in printer to print sample results or complete certification reports directly from instrument
Dust Aerosol Generator 3410
The Dust Aerosol Generator Model 3410 disperses dry dust and powders for applications that need continuous and stable dosing with high accuracy. These defined test aerosols are commonly used in aerosol science, filter testing, industrial processes, and quality assurance tasks. The interchangeable dispersing units make it possible to disperse different materials (e.g. soot, TiO2 , cellulose, or ISO 12103 test dust) at different output concentrations. A pressurized cover keeps the material dry even in locations with higher ambient humidity.
Primary Calibrator 4046-AC
ISO 17025 Accredited The Primary Calibrator 4046 has a range of 2.5 to 300 liters per minute (L/min).
