Can We Save The World ?Measuring residential temperatures using a digital infrared thermometerAn excellent way to measure surface temperatures both inside and outside your home is to use a digital infrared thermometer. These small portable hand held battery powered units cost from around $100, they focus the infrared radiation emitted from an area of a remote measured surface onto an infrared sensor and continuously convert it to an accurate digitally displayed temperature.

The area measured is directly proportional to the distance between the infrared thermometer and the surface being measured, typically if this distance is 60 inches the diameter of the measured area is 6 inches, if the distance is 20 feet the diameter of the area measured is 2 ft. IR thermometers are non-contact devices that can be used for remotely measuring residential temperatures and can also be used to rapidly locate areas hotter or colder than their surroundings so are ideal for locating cold or hot air leaks and poorly insulated areas. When attempting to cool you home naturally infrared thermometers are very useful as they rapidly and accurately indicate the temperature of any area they are pointed at. A digital infrared thermometer together with an ‘air flowometer’, - a hand held partially unrolled toilet paper roll, allows you to identify which external windows and doors to open to achieve the fastest cooling rate for your home. Infrared thermometers are also ideal for measuring rotating, electrically live, very hot, or hard-to-reach objects. As well as measuring residential temperatures infrared thermometer uses include measuring body temperatures, cooking temperatures, outdoor grill temperatures, refrigerator and freezer temperatures, liquid temperatures, clothes iron temperatures, oven temperatures, soldering iron temperature, troubleshooting engines by locating hot or cool spots, measuring the temperature of electronic components, and in the diagnosis of heating and cooling systems.
