Facts

By performing a quick and simple test using a
Sentinel turbidity* tube your heating specialist
can easily find out if your system is clean or dirty.
Fill the turbidity tube with
system water to line A. If
necessary, gradually decant
the water from the tube
until the two circles in the
base of the tube are visible
from above. To determine
how dirty your system is
simply note the level from
the side of the tube.
If circles are visible from
here (line A) the system is
clean.
If circles are visible
within this area (between
line A and C) the system
is dirty
If circles are visible
from here (line C or below)
the system is very dirty
If your system is dirty it will
need to be cleaned with
either X300 or X400, and
protected with X100.
Is your system clean or dirty?
* Turbidity is the cloudiness or haziness of
a fluid caused by individual particles
(suspended solids). The measurement of
turbidity is a key test of water quality.
