OS-XL
$
3950
The OS-XL is a 2-dimensional 
infrared thermometer equipped with 
a newly developed 64-element 
thermopile array sensor. The OS-XL 
is not just another non-contact 
temperature measurement 
device–the OS-XL allows the user to 
view and verify the measurement 
subject on the LCD screen while 
simultaneously measuring the
temperature at 64 points. The OS-XL 
can actually display and save data 
with a graphic representation of the 
temperature distribution overlaid on 
an image of the subject being 
measured. Furthermore, device 
operation is extremely easy, similar 
to that of a digital camera, greatly 
increasing operation efficiency. 
The OS-XL offers exceptional 
functionality that has never been 
available before at this amazingly 
low price. Combining OMEGA’s 
original technologies and concepts, 
the OS-XL takes the lead in the field 
of temperature measurement.
Simultaneously 
record both image 
and temperatures at 
64 points while viewing 
the object being 
measured!
Complete with 
16MB flash card, flash
card reader, hand strap,
batteries, AC adaptor,
carrying case, video 
cable and manual.

Conventional Infrared 
Thermometers
Can measure the temperature 
at a target point.
Thermography
Provides detailed information 
about the temperature 
distribution of an entire object.
The OS-XL
Provides an easy-tounderstand image display that 
simultaneously shows the image 
of the measurement subject and 
the temperature distribution at 64 
measurement points.
The Newly Developed 64-Element Thermopile Array
A thermopile is the heart of most of today's leading infrared thermometers. 
The thermopile array consists of a matrix of multiple thermopile elements, 
but attempts to put this technology into practical application have been 
hindered by size and sensitivity problems. OMEGA has managed to 
overcome these problems using semiconductor processing based 
micromachining, successfully developing a micro-size, high-sensitivity 
thermopile. The resulting 64-element thermopile array consists of an 
8 x 8 matrix of 0.5 mm
2
(0.02"2) elements, the first such matrix in the 
world to be put into practical application.

The true value of the OS-XL lies in its ability to display 
temperature distribution on an image of the measurement 
subject. The OS-XL provides even greater functionality.
The image of the object being measured is divided 
into a 64-frame grid. The temperature distribution is 
displayed in corresponding colors on the grid lines 
framing each area. Temperature is measured in each 
frame. The cursor can be used to select a specific 
frame in order to display the temperature for that area 
in 0.1° increments. The OS-XL provides easy 
operations for both measuring and recording data. 
The OS-XL also provides a diverse range of settings 
functions and data options supporting "smart 
temperature measurement" with its enhanced 
functionality.
A Variety of Display Modes, Each With a Diverse Range of Settings
The user can freely switch between 
image display modes.
The user can select between 3 types 
of image modes: Visible Image Display, 
64-Frame Grid Mosaic Display, and 
64-Frame Gridline Display.

registered trademarks of their respective corporations.
Convenient, 
Detailed Settings
The OS-XL provides a 
variety of convenient 
functions including a 
temperature scale that 
can be user-set to a 
range from -50 to 1000°C. 
Upper and lower alarm 
limit settings are used to 
issue an audible alarm 
and an alarm message 
if the temperature exceeds 
the set range. A color 
scale display corresponds 
to an image of the 
temperature range of 
the measurement subject.
The infrared lens and visible light 
lens are at different locations on 
the OS-XL, so parallax can occur 
between the temperature display 
area and the actual location 
being measured. However, a 
3-stage (0.5 m [1.64'], 1 m 
[3.28'] and infinity) 
measurement distance 
setting can be used to 
compensate for the parallax.

Effectively Utilize Data in an Expandable System
Measurement conditions can be easily recorded using the OS-XL’s video output.
The OS-XL is equipped with a video output jack, so the measurement conditions 
can be easily recorded on videotape or monitored on a large-screen TV.
(Please use the video cable included with your unit for video output.)
The OS-XL saves data in formats 
that can be easily edited by computer.
The data saved on the CF card can be read by 
most computers. It is easily viewed and edited 
without using specialized software. With 
Microsoft Excel, the image and measurement 
data can also be analyzed and used to 
generate illustrated reports.
(A CF card reader (included) is needed to access 
the stored data by computer.)

All recorded data is saved on a Compact Flash (CF) card.
The OS-XL is equipped with a compact flash card slot so that 
image data and measurement data can be easily saved and 
stored. All of the measured values for each grid frame are saved 
for each image. The OS-XL can simultaneously record data for 
64 measurement locations.
(Images are saved in JPEG format, and measured values are 
saved simultaneously as a CSV-format file.)

Convenient, Easy-to-Use, High-Performance Functions
• Sharp, bright, high-visibility TFT 
color LCD monitor
The bright 3.8-inch TFT color LCD monitor provides 
sharp, clear, high-resolution images. The LCD image 
is easy-to-see, even when making measurements 
outdoors. The sharp display also provides a clear 
numeric display of the measurement data.
• Automatic continuous measurements
With the "Logging" function, the OS-XL can be used to 
make automatic continuous measurements at a fixed 
location, such as the continuous monitoring of 
temperature fluctuations at a specific location. 
(The OS-XL can be mounted on a standard 
camera tripod.)
• Automatic power shutoff function
This energy-efficient measurement gage can be set 
to turn off automatically if no buttons are pressed for 
1 minute.
Easy Operation, with the Feel 
of a Digital Camera
In addition to making measurements, the OS-XL also 
makes it easy to save data—just line up the object 
being measured in the LCD monitor and press the 
"Save" button. The lightweight, compact body of the 
OS-XL makes it an exceptionally convenient 
measurement device.
