The test method employed by the MK-2
is known as the “Go/No Go” Test and
provides very fast and accurate results. To
simulate micro-organisms, a microfog or
series of smoke-like particles is generated
within the filter tester from non-toxic
saturated synthetic hydrocarbons. These
hydrocarbons form micro drops of 0.2 to 2.5
μm.

This fog is then applied under pressure
from an integrated compressor to the
filter being tested. The fine fog particles
quickly penetrate even the smallest leaks
in the filter providing immediate visual
identification.

A filter test can be performed in less than
a minute. The procedure is simple and
requires no special knowledge or skills.

After the filter test, the micro drops
evaporate without leaving any trace in the
filter element.
