The EMS water trap assembly
(Fig. 1) is essencial for road
testing, Dyno use, Diesel testing,
motor cycle testing, and two
cycle fuel testing. This accessory
will prolong the analyzer life by
pulling more moisture out of the
sample gas.
The Y-Valve assembly (Fig. 2)
was designed for pre-catalytic
converter testing. With the real
benefit being able to hook up
both pre & post cat sample hose
& probes. And swich between
both readings at the analyzer,
which saves you time. Also check
back pressure on the pre-cat side
at the analyzer with our inline
pressure gauge (Fig.3)

threaded end. The kit includes the pop nut insert tool, 1/4-20 mandrel, box of 40 nuts, 50
