Basics

4 Basics

4.1 Measurement of Infrared Temperature

All objects emit an amount of infrared radiation according to their surface temperature. The intensity
of the infrared radiation changes according to the temperature of the object. Depending on the
material and surface properties, the emitted radiation lies in a wavelength spectrum of approximately
1 to 20 µm. The intensity of the infrared radiation (”heat radiation”) is dependent on the material. For
many substances this material-dependent constant is known. It is referred to as ”emissivity value”
(see section 10.2 Typical Emissivity Values, page 56.
Infrared thermometers are optical-electronic sensors. These sensors are able to detect ”radiation of
heat.” Infrared thermometers are made up of a lens, a spectral filter, a sensor, and an electronic signal­processing unit. The task of the spectral filter is to select the wavelength spectrum of interest. The
sensor converts the infrared radiation into an electrical signal. The signal processing electronics
analyzes the electrical signal and converts it into a temperature measurement. As the intensity of the
emitted infrared radiation is dependent on the material, the required emissivity can be selected on the
sensor.
The biggest advantage of the infrared thermometer is its ability to measure temperature without
touching an object. Consequently, surface temperatures of moving or hard to reach objects can easily
be measured.

4.2 Emissivity of Target Object

Determine the emissivity of the target object as described in section 10.1 Determination of Emissivity,
page 56. If emissivity is low, measured results could be falsified by interfering infrared radiation from
background objects (e.g., heating systems, flames, fireclay bricks, etc., close beside or behind the target
object). This type of problem can occur when measuring reflecting surfaces and very thin materials
such as plastic films and glass.
This measuring error can be reduced to a minimum if particular care is taken during installation, and
the sensing head is shielded from these reflecting radiation sources.

5 Operation

5.1 Quick Start

To use the instrument right away, complete the following steps:

1. Point the instrument at the object the user wants to measure (as perpendicular as possible to
the object) and pull the trigger. The current temperature (in °C or °F), emissivity value, and
maximum and minimum measured temperature are displayed.

2. Change the emissivity value to correspond to the targeted material by pressing the <F1> key

twice to show the target material table. Press the ▲ and ▼ buttons to select the target material.

For complete definitions of the instrument’s
explanation of operation, refer to the later sections.

5.2 Overview

Portable infrared thermometers measure surface temperatures without touching the surface. They
collect the infrared energy radiated by a target and compute its surface temperature. They also
compute the running average, and maximum/minimum/differential temperatures and present them
on a digital display in either degrees Celsius or Fahrenheit. The instrument is battery-powered or can
be powered by a computer’s USB interface. Internal memory circuits store temperature data for later
recall, and a data-logging feature allows users to store and multiple temperature, emissivity, and
alarm readings (valuable for comparative analysis).

The following figure shows the features of the portable infrared thermometer.

5.3 Distance and Spot Size

As the distance (D) from the object being measured increases, the spot size (S) of the area measured by
the instrument becomes larger. For the relationship between distance and spot size (D:S), see section

3.2 Optical Charts, page 14.
During measurements, please make sure that the target is larger than the instrument’s measurement
spot size at that distance. The smaller the target, the closer user should be to it.

5.4 High Temperature Nose

The instrument has a specially designed nose with high temperature resistant plastic material to avoid
damage from high temperature targets. On the other hand, please avoid over exposure when aiming
at a high-temperature target.
There is a temperature sensor inside the nose. During measurement, the instrument is monitoring the
temperature of the nose. If it is too hot, there will be a warning on the LCD display (ambient highlight
display and backlight change to red plus audible buzzer). Please move the unit away from the high­temperature target when seeing this alarm.

5.5 Power Supply

The instrument is powered by a battery or USB cable when connect to the PC. The battery is located in

5.6 Display

The display retains the last infrared measurement for 20 s when the trigger is released and <HOLD> is
shown on the display. To hold the infrared temperature, release the trigger until <HOLD> shows on
the display.

5.7 Sighting

5.7.1 Dual Laser

All models use a dual laser method to show the measurement spot position and size. The two laser
points show the diameter of the spot circle, with the middle laser point as the center of the spot circle.

5.7.2 Red Dot Scope

The scope models for the Raynger 3i Plus series provide an additional red dot scope; the measurement
target can be seen through the scope. That aiming system can be used when the laser points are hard
to see due to the brightness of the target.
The scope's red dot shows the center of the measuring spot circle, which does not display on the real
object under measurement.
The intensity of the field sight can be adjusted by rotating the knob on the top of the instrument while
keeping the brightness of the red dot. This function is helpful for the user to clearly see the red dot
position when the instrument is measuring high-temperature objects.

If the scope's red dot does not match with the circle of the two laser points, use the following
adjustment method:

1. Open the two circular rubber caps on the top of the unit, and the scope's two adjustable
screws are shown.

2. Affix the unit to a tripod.

3. Aim at a target 4 m (13 ft.) off in the distance, like a wall, for viewing the two lasers clearly.

4. Adjust the two screws on the aiming scope to the center of the two laser points. Please try to
look straight through the aiming scope.

5. Remove the unit from the tripod.

6. Close the two circular rubber caps.

Warning: Please do not use the unit with the two rubber caps open, since unexpected contact with
the screws may introduce noise pulse to the units, resulting in noise readings or disorder of the
display

5.8 Temperature Records

The instrument can store measurement records, including time, date, emissivity, and measurement
record numbers. It can store 1,000 records for basic test data, 10 pcs trend display and 300 records for

7.6 Recorded Data

The recorded data is divided into three groups: <Basic test data>, <Trend data>, and<Profile test data>.

• <Basic test data> is the test data without dedicated settings. The user can record random
measurement data in this area with a maximum of 1,000 records.

• <Trend data> is saving data under trend mode, which should include three-screen data with
360 test values. The minimum interval for trend is 20 ms. In this mode, the user can capture

300 records. By using the load value of each profile, these test data have been divided by
group according to the profile setting in the PC software. The user can find the temperature
distribution status in one group. When starting the measurements, the user can easily recall a
profile instead of having the need to set each parameter individually such as emissivity or
temperature alarm thresholds.

9.2 Lens Cleaning

The user should periodically clean the instrument’s front window.
A dirty front window (lens) can cause temperature measurement errors. The window is fragile, and
care should be taken when cleaning it to prevent scratching. Use camera lens or eye glass tissues to
clean the window.
Periodic cleaning can be done by completing one or more of the following in one of the following
ways:

• Blow loose particles off the front window with clean compressed air.
Note: Unfiltered compressed air, as well as user’s own breath, can cause condensation on the
front window, which can trap dust particles instead of removing them.

• Gently brush off particles with a soft camelhair brush.

• Thicker contaminants can be cleaned with water and a camera lens tissue.

• Fingerprints and grease can be removed either with isopropyl alcohol, Ethanol, Xylene,

Acetone, or Kodak
lens tissue until user see colors on the surface, then allow to air dry. Do not wipe the surface
dry, as this may scratch the surface.

Can cause severe damage to the front window!

10.1 Determination of Emissivity

Emissivity is a measure of an object’s ability to absorb and emit infrared energy. It can have a value
between 0 and 1.0. For example, a mirror has an emissivity of 0.1, while the so-called “Blackbody“
reaches an emissivity value of 1.0. If a higher than actual emissivity value is set, the output will read
low, provided the target temperature is above its ambient temperature. For instance, if the set value is

0.95 and the actual emissivity is 0.9, the temperature reading will be lower than the true temperature.
An object’s emissivity can be determined by one of the following methods:

1. Determine the actual temperature of the material using an RTD (PT100), a thermocouple, or any
other suitable method. Next, measure the object’s temperature and adjust emissivity setting until
the correct temperature value is reached. This is the correct emissivity for the measured material.

2. If possible, apply flat black paint to a portion of the surface of the object. The emissivity of the
paint must be above 0.98. Next, measure the temperature of the painted area using an emissivity
setting of 0.98. Finally, measure the temperature of an adjacent area on the object and adjust the
emissivity until the same temperature is reached. This is the correct emissivity for the measured
material.

10.2 Typical Emissivity Values

The following table provides a brief reference guide for determining emissivity and can be used when
one of the above methods is not practical. Emissivity values shown in the table are only approximate,
since several parameters may affect the emissivity of a material. These include the following:

1. Temperature

2. Angle of measurement

3. Geometry (plane, concave, convex)

4. Thickness

5. Surface quality (polished, rough, oxidized, sandblasted)

6. Spectral range of measurement

7. Transmissivity (e.g., thin films, plastics)

Table 8: Typical Emissivity Values

To optimize surface temperature measurements, consider the following guidelines:

• Determine the object emissivity using the instrument, which is also to be used for
measurements.

• Avoid reflections by shielding the object from surrounding temperature sources.

• For higher temperature objects use instruments with the shortest wavelength possible.

• For translucent materials such as plastic foil or glass, ensure that the background is uniform

and lower in temperature than the object.

• Hold instrument perpendicular to surface whenever emissivity is less than 0.9. In all cases, do
not exceed angles more than 30 degrees from incidence.

• For 1M and 2M models, avoid measurements in high ambient light conditions.
