CLKT C-Range

Infrared Window

for outdoor applications Technical Data

Increase the safety and speed

of electrical thermography

If you are concerned about arc-flash but

wish to continue with your infrared ther-

mography program, infrared windows are

the answer. These arc-resistant, outdoor

certified, infrared windows allow thermal,

ultraviolet, visual and fusion technologies to

be used without exposing personnel to live

equipment.

Exclusive to Fluke IR Windows,

allows you to inspect your equip-

ment with four different types

of cameras. Provides maximum

flexibility to upgrade or swap out

inspection cameras without any

IR Window replacement. No other

IR Windows manufacturer gives

you that flexibility.

AutoGround™

Automatically grounds at instal-

lation for maximum safety and

compliance. No additional steps

or testing is required. Only avail-

able on Fluke IR Windows.

Quadraband™

OPTIC TECHnOLOGY

All infrared windows from Fluke use the unique

Quadraband™ multispectral optic, allowing

inspection with any camera for total flexibility both

now and in the future.

•

Engineered and tested to withstand electric-arcs

up to 50 kA for 30 cycles.

•

Certified by UL & CSA for Type 3/12 (Outdoor)

environments in North America and Canada, the

C-Range windows are tested to withstand the

long term aging effects of UV exposure.

•

Certified by SIRA Certification IP65 (Outdoor)

environments in Europe.

•

The CLIRVU® coating—exclusive to Fluke

Windows—seals the optic prior to assembly to

protect against moisture degradation.

•

Own a Fluke Camera? The Quadraband™

optic is IR-Fusion® compatible, allowing the

thermographer to see potential problems in

visual light and thermographic mode.

•

Got more than one window per panel?

Each C-Range window is delivered with an

identification plate attached for unique, on-site

numbering for rapid location confirmation and

faster repairs.

•

Each infrared window comes complete with a

security access key, installation instructions and

self-adhesive drilling template.

Detailed specifications

Why is available area important?

Understanding the difference between “Optic Diameter”

and “Available Area” gives the thermographer a measure

of how much infrared energy is passing through the

window. The more energy, the better the reading. The

entire area of a crystal IR Window is available for infrared

transmission for optimum repeatable results.

Mesh grids may have a larger “optic diameter” but the

grid itself blocks the IR signal. The amount of radiation

available to the camera via mesh windows is significantly

reduced and the signal may be irregular.
