5 Ways to Make Better Measurements with an Infrared Thermometer
Infrared thermometers are handy at times of pandemic. These ingenious devices can detect temperature quickly without needing contact with the skin.
Infrared thermometers have many uses. They don't just read the human body temperature. They're also used in the kitchens, manufacturing floors, and so on. Infrared thermometers can be useful, especially if they get accurate readings. However, there are rare times when infrared thermometers don't take accurate readings. Fortunately, there are ways to avoid wrong readings.
Below are the five ways you can do to get your Infrared thermometer read better.
1) Make sure to measure within your Infrared thermometer's "distance-to-spot" (D:S) ratio
Every infrared thermometer has its own "distance-to-spot" ratio. The "distance-to-spot" ratio is the allowed diameter of the area for reading. If you veer from the device's "distance-to-spot" ratio, you will not be getting an accurate result because your device will pick up other heat signatures.
To avoid this mistake, check your device's "distance-to-spot" ratio and the maximum distance between the person's forehead and your infrared thermometer.
2) Keep the laser pointed in the center of a person's forehead
Some infrared thermometers have laser pointers. The laser shows the approximate center of the measurement area.
The laser is only a pointer that lets you know the center to which your infrared sensor is pointed at. Lasers don't read temperatures. Also, infrared thermometers don't just read the spot where the laser is on; rather, it reads a wider area.
To help your infrared thermometer get an accurate reading, point the device's laser to the center of the person's forehead.
3) Paste an electrical tape on a shiny object's surface you're trying to temp read
Infrared thermometers are often good in reading temperatures because they're designed to do so. However, infrared thermometers find it particularly difficult to read shiny, reflective, or illuminating objects.
You can combat this problem by pasting an electrical tape on the surface of a shiny object you're trying to get a temperature on.
4) Clean your infrared thermometer's optics
The clearness and cleanliness of your infrared thermometer's optics matter when it comes to temperature-reading accuracy. For example, if there is a thick fog or accumulation of aerial dust between your target and your infrared thermometer device, some of the infrared energy will sway or deflect.
Another example is, a dirty or scratched optic (or lens) can lessen the temperature reading accuracy of the device because it won't properly sense IR energy.
That's why it's important to keep your infrared thermometer free from dust and scratches. Use a cloth to wipe your device's optics gently.
5) Let your infrared thermometer hover for awhile
For the highest accuracy, don't put down your device quickly. Let your infrared thermometer hover for a while to get the best possible temperature reading accuracy.
Look for the device's instructional pamphlet on when to put down the device and follow them.
The infrared thermometer needs time to adjust to reading your subject's temperature properly. Remember, your surroundings also have a temperature that can affect your infrared thermometer’s reading.
