OPENING:
• Like many testing situations, you need an
instrument to “see” what you want to test.

Is It Hot? Not? Or too hot?
Lots of Long Range Testing -- 1500 feet?

Questions
Is this your next
fire or off air
problem?
Introducing New Concepts
• Now You Can See Heat
• No More Burned Fingers
• Better Than A Non Contact IR Thermometer
• High Resolution Pixel by Pixel Temperatures
• Interchangeable Telephoto Lenses
• Long Distance Imaging Day Or Night
Test Equipment That We Use
Every Day

The Latest Piece Of Test Equipment 
• No More Guessing What Is Hot And What Is Not
• Never burn your fingers again
• Watch thermal events as they unfold
• Thermocouples and Mercury bulbs are gone
the way of the Dodo bird
• Permanent color images of tested
components
• Test refrigeration / cooling systems too
This Is How It’s Done
Infrared Thermography:
• Infrared Imaging (Thermography) is not a new
technology but now it is available to the mass
public with better features, color interpolation
and lower cost than ever before.
• There are low cost toys you can own and high
priced feature packed models that are often
more cost effective to rent with an operator
who is skilled in testing and can give you a
report.
What Can We Test:
• Motors, Transformers, Pump Bearings & Seals
• Refrigeration Compressor Cases, Evaporator and
Condenser Coils
• Relays, Terminals, Bolted Connections
• Transmitter Stack Discharge Temperatures
• Magnet Body Coils, Cavity Hot Spots, Filter
Heating, Water Flow Restrictions, Beam Supply
Oil Levels, Water Tank Levels, Cabinet Finger
Stock Heating, Tuning Component Heating
What Else Can We Test:
•
•
•
•
•
•
•
•
•
Generator Engine Blocks and Alternators
Circuit Breakers and Panel Board connections
Ground and Neutral Heating
Wiring Troughs, Split Bolts and Wire Nuts
Heat Exchangers and Blower Motors
Coaxial Cable and Rigid Transmission Line
Coaxial and Waveguide Switches
Dummy and Reject Loads
Hybrid Couplers and Antennas
Likely Suspects

Is It Hot? Not? Or Too Hot?
• With Infrared Thermography you can
differentiate between objects that are close
together where conventional hand held noncontact IR thermometers will not work.
• Detail heat signatures down to the component
level is a valuable troubleshooting tool
• Thermal analysis of objects dozens to hundreds
or thousands of feet away are now possible
Long Range Testing:
Long Range Lens
Normal Range Lens
Long Range Testing:
Notice the heating of the
fiber rod metallic joint
connections
Antenna issues can be easy
to “SEE” and can give an
indication that more invasive
Line Sweeping may be
needed.
Long Range Testing:
Night time images with on
board illumination or
ambient light give good
results.
See how the temperature of
the transmission line is easy
to differentiate from the steel
of the tower and lights.
Long Range Testing:
• Tremendous detail is
available even with long
lens applications.
• Dusk images show thermal
loads on the steel and
other components
The long range Infrared Images
are accompanied by a
standard lens range color
images for easy reference.
Images taken from over 2500
feet away 
