UT300 SERIES

Non-contact Infrared Thermometer

Introduction

The Model UT300A and UT300B Infrared Thermometer

(hereafter, the “Thermometer”) can determine the

surface temperature by measuring the amount of

infrared energy radiated by the target’s surface. They

have different distance to spot (D:S) figure and different

temperature range, details see the contents.

The Thermometers are non-contact infrared thermom-

eter with low consumption design so that they can be

used for a longer time, which can solve the frequently

changing battery and low battery issues during

measurement. Intelligent design can make measure-

ment easier and quicker.

Safety Information

Operating Manual

Caution

To avoid damaging the thermometer or the equipment

under test protect them from the following:

EMF (electro-magnetic fields) from arc welders,

induction heaters, etc.

Static electricity.

Thermal shock (caused by large or abrupt ambient

temperature changes – all 30 minutes from the

Thermometer to stabilize before use).

Do not leave the Thermometer on or near objects of

high temperature.

How the Thermometer Works

Infrared thermometers measure the surface tempera-

ture of an opaque object. The Thermometer’s optics

sense infrared energy, which is collected and focused

onto a detector. The Thermometer’s electronics then

translate the information into a displayed temperature

reading which appears on the display. The laser is

used for aiming purposes only.

Operating the Thermometer

The Thermometer turns on when you press the trigger.

The Thermometer turns off when no activity is detected

for 8 seconds.

To measure temperature, aim the Thermometer at the

target, pull and hold the trigger. Release the trigger to

hold a temperature reading.

Be sure to consider distance-to-spot size ratio and filed

of view. The laser is used for aiming only.

Locating a Hot or Cold Spot

To find a hot or cold spot, aim the Thermometer

outside the target area. Then, slowly scan across

the area with an up and down motion until you

located the hot or cold spot. See Figure 5.

Distance and Spot Size

As the distance (D) from the target being measured

increases, the spot size (S) of the area measured by

the unit becomes larger. The spot size indicates

90% encircled energy. The maximum D:S is

obtained when the Thermometer is 1000mm (100 in)

form the target resulting in a spot size of 20mm (2

in).

Field of View

Make sure that the target is larger than the spot

size. The smaller the target, the closer you should

be to it. Suggested distance less than 75% of the

theory value.

Maintenance

Changing the Battery

To install or change the 9V battery, open the battery

compartment the battery.

Cleaning the Lens

Blow off loose particles using clean compressed air.

Carefully wipe the surface with a moist cotton swab.

The swab may be moistened with water.

Cleaning the Housing

Use soap and water on a damp sponge or soft cloth.

To avoid damage to the Thermometer, do not soak the

unit into water.

Caution

To avoid damaging the Thermometer, do NOT

submerge it in water.

Specifications

Troubleshooting

Warning

A warning identifies conditions and actions that pose

hazards to the user. To avoid electrical shock or

personal injury, follow these guidelines:

Do not point laser directly at eye or indirectly off

reflective surfaces.

Before using the Thermometer inspect the case. Do

not use the Thermometer if it appears damaged. Look

for cracks or missing plastic.

Replace the battery as soon as the battery indicator

appears.

Do not use the Thermometer if it operates abnormally.

Protection may be impaired. When in doubt, have the

Thermometer serviced.

Do not operate the Thermometer around explosive

gas, vapor, or dust.

To avoid a burn hazard, remember that highly

reflective objects will often result in lower than actual

temperature measurements.

Do not use in a manner not specified by this manual

or the protection supplied by the equipment may be

impaired.

Emissivity

Emissivity describes the energy-emitting characteris-

tics of materials. Most organic materials and painted

or oxidized surfaces have an emissivity of about 0.95.

If possible, to compensate for inaccurate readings that

may result from measuring shinymetal surfaces, cover

the surface to be measured with masking tape or flat

black paint (<150 / 302 ) and use the high emissiv-

ity setting. Allow time for the tape or paint to reach

the same temperatures as the surface beneath it.

Measure the temperature of the tape or painted

surface.
