GENERAL DESCRIPTION
Infrared
radiation
emitted
from
an
object
depends
on
its
tem-
perature.
The
HI 99550
infrared
thermometer
employs
this
tech-
nology
to
measure
the
surface
temperature.
Infrared
measure-
ments
are
extremely
practical
with
an
instantaneous
response
time.
The
non-intrusive
nature
of
the
measurements
can
trans-
late
itself
into
substantial
savings
in
industries
where
products
are
sealed
or
pre-wrapped.
This
type
of
non-intrusive
measure-
ment
is
also
useful
when
the
surface
temperature
is
high,
for
difficult-to-reach
places
or
due
to
hygiene
requirements.
In
order
to
measure
the
temperature,
simply
point
to
the
product
or
the
spot
and
hold
down
the
measurement
key.
The
measured
value
will
be
immediately
displayed
on
the
LCD.
HI 99550
is
designed
with
a
wrist-strap
and
ergonomic
shape
for
greater
ease
of
use.
The
fast
response
time
and
the
HOLD
function
make
this
infrared
meter
particularly
attractive
for
repetitive
tests
in
the
factory
or
on
the
production
line.
Two
models
are
available
for
measurement
in
degree
Celsius
or
Fahreneit (
HI 99550-00
and
HI 99550-01
).
Hanna Instruments reserves the right to modify the design, construction
and appearance of its products without advance notice.
