Infrared Thermometers
Infrared thermometers are the ideal tool for temperature diagnostics and inspection. Infrared thermometers measure temperature under circumstances where other sensors cannot be used or do not produce accurate data.
What is Spot Ratio
When choosing an Infrared Thermometer (IR) one of the most important features to look at is the Distance to Spot Ratio (D: S). The D: S Ratio indicates the size of the measurement field that a noncontact infrared thermometer uses to provide a temperature reading. The larger the ratio the better the resolution and the smaller the area that can be measured. An IR Thermometer with a D: S of 12:1 will measure a 1” diameter at a distance of 12” away. A D: S of 50:1 will measure a 1” diameter at a distance of 50”. Since this is a ratio it is also true that a D: S of 8:1 will measure a 1’ diameter at a distance of 8”. When measuring surfaces at greater distances the larger the D: S Ratio the more accurate you readings will be.

Upgrading from a Infrared Thermometer to a Infrared Camera
Temperature is often an early indicator of developing problems and can be used as a screening tool for situations that require further investigation. Infrared (IR) Thermometers also known as non contact thermometers allow you to stay a safe distance away and get fast, accurate readings across a wide range of temperatures.
IR Thermometers were designed for applications that require instantaneous readings of temperatures. These could be in hard to reach locations that may require a ladder, or were the objects are too hot to get close to. In home inspections they can be used to check the temperatures of breakers, registers, or scanning surfaces looking for rises or drops in temperatures that could be indicators of moisture behind the surface or poor insulation.
There are numerous benefits to using IR Thermometers but there are drawbacks as well. Where the IR Thermometer offers fast, accurate readings that can be made at a distance; you are also restricted by the parameters of the thermometer that determine the size of the spot where the temperature is being taken.
Infrared Cameras take the inspection to the next level; not only do the show temperatures of specific spots they show that temperature along with the temperatures of the entire breaker box, wall or exterior of a house. The ability to look at entire surfaces is the easiest and quickest method to detect energy waste, moisture and electrical issues in buildings. The IR Camera shows a picture of where the problems are and help the inspector properly diagnose those situations.
