Automated Filter Tester

3140 - TSI Inc.

Automated Filter Tester 3140 utilizes the same, proven, oil-aerosol generator technology found in Models 8127 and 8130. It produces oil aerosol without heat, so a variety of oils can be used. Two Condensation Particle Counters (CPCs) simultaneously count upstream and downstream particles. This enables quick, accurate, and repeatable measurements of filters with efficiencies as high as 99.999999% (eight 9’s), or penetrations down to 0.000001%.
