The OMEGA
instruments for difficult and demanding
high-temperature, 300 to 3000°C
(572 to 5432°F) applications. It is ideally suited
for measurement and control applications
involving metals, glass, semiconductors,
and more. The iR2 is extremely fast and
accurate with a response time of 10 ms
and accuracy of 0.2% FS. Despite its
extraordinary technological sophistication and
performance, the iR2 is also incredibly user
friendly and simple to configure. The iR2 is
designed to the highest-quality standards and
is backed by a 5-year warranty.

2-Color Ratio Measurement
The iR2 measures temperature using a
2-color ratio technique in which a temperature
is computed from the ratio of 2 different
infrared frequencies, unlike a standard
infrared thermometer that measures the
absolute amount of infrared energy. The
2-color ratio technique is essential for accurate
measurements in many common applications:
when the target is obscured by smoke or steam,
when the target is viewed through a window or screen
that reduces energy, or when the emissivity of the target is
unknown or changes.
Unlike a standard infrared thermometer that determines an
average temperature for everything within its field of view, the
iR2 does not require that the target completely fill the lens field
of view as long as the temperature of the target is higher than
the background or material in the foreground.
This capability allows the iR2 lens to be installed farther
from the target, or outside a window or screen, as well as
to measure temperatures of small and moving targets more
accurately. The iR2 can also be switched to 1-color operation
if required.
Cast-Aluminum or Panel-Mount Enclosure
The iR2 is available in 2 practical packages. The iR2C model is
an extremely rugged cast-aluminum enclosure (with NEMA 4
rating) that can be mounted on any surface and is powered by
20 to 36 Vdc or 24 Vac. The iR2P model is a
package with a NEMA 4 front bezel for rack or cabinet mounting
with other instrumentation, and runs on 90 to 240 Vac or 110 to
375 Vdc power.

Full PID Control
The iR2 is much more than an infrared transmitter. It is a
complete autotune PID temperature controller an extremely
compact enclosure (an important, unique feature). The iR2
features a totally programmable analog output that can be
programmed within a range of 0 to 10 Vdc or 0 to 20 mA.
The analog output is selectable as either a control output
or as a calibrated retransmission of the temperature. The
iR2 also offers a choice of 2 form "C" (SPDT) relays or solid
state relays for controlling or alarms. The control functions
feature the full suite of capabilities from simple on/off to
full proportional integral derivative (PID) control. Instead
of connecting a simple infrared transmitter to a separate
temperature controller, the iR2 can do it all.
Big, Bright Display
The iR2 features a big, bright LED dual display. The smaller
numbers display the setpoints or alarm points. The larger
numbers (a full 21 mm [0.83"] high) display the measured
temperature. The display can be programmed to change color
between GREEN, AMBER, and RED at any setpoint or alarm
point, and the change in color is quickly seen from a distance.

Fiber Optics
The iR2 comes with a compact NEMA 4 lens
and a flexible fiber optic cable assembly. With the iR2, it’s
possible to measure the temperature of targets that would
simply not be visible with conventional instruments. The
fiber optic cable and lens allow the instrument electronics
to be kept away from the target environment where it would
be subjected to higher temperatures, smoke, dust, steam,
or powerful electromagnetic emissions such as those
generated by induction heating.
Both the stainless steel lens assembly and rugged cable
assembly can be replaced in the field without returning the
instrument for recalibration (a unique feature). The lens can
operate in ambient temperatures up to 200°C (392°F) without
external cooling. The variable-focus lens can focus on targets
from any distance between 200 mm (8") and more than 4 m
(14'). The 25:1 field of view is ideal for most applications.
OMEGA also offers a wide selection of compatible applicationspecific lens assemblies and fiber optic probes developed
during 3 decades of experience servicing the most demanding
infrared temperature applications.
Unique Built-In Laser Sight
The iR2 features a unique built-in “through-the-lens” laser that
shows the operator precisely what the lens is seeing (spot
size). This innovative laser illuminates the precise spot on
the target that the lens is viewing, and allows the operator to
focus on the target with absolute precision. The laser can be
turned on to sight the target and off to make a measurement
with the simple pushbutton on the front panel, or remotely
via network or serial communications. The cable and lens do
not have to be disconnected and connected to a separate
apparatus to provide a conventional or laser light for sighting.
