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.

Temperature Measurement
To obtain the temperature of
an object, simply aim the sen-
sor in the direction of the
object. Keep the ON/OFF
button pressed for a few sec-
onds until the reading
stabilizes.
The instrument will continue
reading the temperature,
while the ON/OFF button is
pressed. When released, the
instrument freezes the read-
ing for a few seconds and
then switches off automati-
cally.
Reading Distance
The distance between the sensor and the object is an
important factor in the infrared measurement.
The relation between distance/object area of the instrument
is 3:1. This means that the diameter of the measured area is
one third of the distance between the sensor and the object.
For example, if the sensor is 15 cm away from the object, the
instrument measures the temperature of an area with a 5 cm
diameter.
Emissivity
The instrument measures the temperature of objects with an
emissivity of 0.95, which is the characteristic of most sub-
stances such as organic material, water, plastic, fabrics, etc.
BATTERY REPLACEMENT
Battery replacement must only take place in a safe area and
using a 9V alkaline battery.
Simply slide off the battery cover on the back of the meter,
detach the battery from the terminals and attach a new 9V
battery, while paying attention to the correct polarity.
Replace the battery cover.
CE DECLARATION OF CONFORMITY
Recommendations for Users
Before using these products, make sure that they are entirely suitable for the environment
in which they are used.
Operation of these instruments in residential area could cause unacceptable interferences to
radio and TV equipments, requiring the operator to take all necessary steps to correct
interferences.
Any variation introduced by the user to the supplied equipment may degrade the instruments'
EMC performance.
To avoid damages or burns, do not perform any measurement in microwave ovens.
To measure substances that have a polished surface and are
very reflective, the emissivity needs to be compensated.
It is advisable to cover the object with black paint or black
adhesive tape to compensate for the reflectivity.
Precaution
To avoid damage, do not hold the sensor too close to a heat
source, for a long period.
Sensor Cleaning
To maintain the instruments accuracy, it is important that
the sensor lens is kept clean.
To clean the sensor gently pass a humid and non-abrasive
cloth (HI 731318) on the lens.
Low Battery
A blinking V on the
display indicates a low
battery level.
It is recommended to replace the battery soon.
