SFZL-A Touch Screen Digital Display Automatic Surface Tension Meter
1.Description
Intermolecular
forces
form
the
interfacial
tension
or
surface
tension
of
the
liquid,
the
size
of
the
tension
value
can
reflect
the
physicochemical
properties
of
the
liquid
and
its
material
composition,
is
the
coatings,
ink
industry
to
examine
the
quality
of
the
product
is
one
of
the
important
indicators.
Our
company
provides
fully
automatic
tension
tester
based
on
the
principle
of
circular
method
(platinum
ring
method),
used
to
measure
the
surface
tension
of
various
liquids
(liquid-gas
phase
interface)
and
the
interfacial
tension
of
liquids
(liquid-liquid
phase
interface).
This
method
is
widely
used
for
its
advantages
of
simple
operation
and
high
accuracy.
Main
performance
characteristics:
*
Adopting
advanced
electromagnetic
force
balance
force
sensor
with
high
accuracy
and
high
repeatability
characteristics.
*
5-inch
wide
touch
screen
control,
the
current
ambient
temperature,
the
current
tension,
peak
tension,
equivalent
tension
and
other
information
integrated
display,
operation
is
very
simple.
*
At
the
same
time
the
design
of
platinum
plate,
platinum
ring
two
test
methods,
you
can
choose
one
of
them,
you
can
also
choose
two
at
the
same
time.
*
Operation
is
fully
automated,
eliminating
all
human
errors.
The
platinum
plate
automatically
locks
the
liquid
interface,
the
platinum
ring
displays
the
tension
curve,
automatically
locks
the
peak
tension
without
any
conversion,
and
directly
displays
the
tension
value
on
the
screen.
*
Full
range
of
automatic
calibration,
support
weight
weight
correction,
pure
water
tension
correction,
ethanol
tension
correction.
*
Compact
ball
screw
lifting
system,
no
noise,
rising
and
falling
speed
adjustable.
*
Convenient
platinum
plate,
platinum
ring
lifting
bracket,
the
user
is
very
easy
to
uninstall,
at
any
time
you
can
use
standard
weights
to
calibrate
the
accuracy
of
force
value.
*
One-key
tare
function,
the
number
does
not
jump,
zero
position
without
drift.
*
Ambient
temperature
automatic
compensation,
water,
ethanol
as
a
standard,
automatic
conversion
of
the
tension
value
of
the
specimen
at
20
°
C.
