Automated Filter Tester 3140
Request A Quote
Automated Filter Tester Model 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%, or penetrations down to 0.000001%. A filter with 99.9999% efficiency can be tested in less than 15 seconds; higher efficiencies take slightly longer. The data output is displayed on a computer screen and can be automatically saved in a Microsoft Access® data base and downloaded into Microsoft Excel®.

Does TSI design custom filter holders?
TSI does customer filter holder designs when needed. Our standard filter holder is designed for flat sheet media. This standard holder is also used to make gravimetric samples with our special gravimetric sample holder, and to use with a pressure plate. Generally, custom filter holder designs are less expensive for round canisters and more expensive for rectangular cartridges, depending on the design and machining requirements. Consult TSI with filter types to be tested for exact pricing on this. To get exact pricing, we need to either have a filter on hand or have the customer send us a sample filter.
What data is output through the RS-232 interface?
The RS-232 interface outputs the filter's percent penetration, flow rate, and pressure drop in the standard filter test modes of operation. The loading test mode of operation also outputs the upstream photometer reading.
What is DOP?
The actual name for DOP is dioctyl phthalate.
