How to Properly Use a Non-Contact Infrared Thermometer to Get an Accurate Reading
Non-contact infrared thermometers (NCITs) are a convenient and safe way to measure the temperature of objects or people from a distance. They are commonly used in medical settings to quickly and easily check for fever, but they have many other uses as well. To ensure that you get an accurate reading with a NCIT, it is important to follow the proper usage guidelines.
First and foremost, it is important to hold the NCIT correctly. The sensor should be pointed at the center of the forehead or other target area, with the distance between the sensor and the target kept at a consistent range. If the NCIT has a laser pointer, use it to aim the sensor at the target. This is important because the accuracy of the reading can be affected if the sensor is not properly aimed.
Next, make sure that the NCIT is properly calibrated. Some NCITs come with a built-in calibration feature, while others may need to be calibrated manually. Calibration is important because it ensures that the NCIT is measuring temperature accurately. To calibrate a NCIT manually, you will need a reference object with a known temperature, such as a calibration plate or a heated or chilled water bath. Follow the manufacturer's instructions for specific guidance on how to calibrate your NCIT.
It is also important to consider the environment in which you are using the NCIT. NCITs are sensitive to temperature changes and can be affected by ambient temperature. For the most accurate reading, use the NCIT in a room that is at a consistent temperature and avoid using it in direct sunlight or other areas with extreme temperatures. The temperature of the room can affect the accuracy of the reading because NCITs measure the temperature difference between the target object and the surrounding environment.
Additionally, make sure that the NCIT is clean and free of any dirt or debris that could interfere with the accuracy of the reading. Wipe the sensor with a clean, dry cloth before use. This is important because dirt or debris on the sensor can absorb or reflect the infrared radiation being emitted by the target object, which can affect the accuracy of the measurement.
It is also important to consider the distance between the NCIT and the target object. Most NCITs have a recommended distance range for accurate measurement, which is usually listed in the manufacturer's instructions. Make sure to follow this recommendation to ensure that you get an accurate reading. The distance between the NCIT and the target can affect the accuracy of the measurement because the amount of infrared radiation emitted by the target decreases as the distance increases.
Another factor to consider is the type of target being measured. Different materials and surfaces can absorb or reflect infrared radiation differently, which can affect the accuracy of the measurement. For example, shiny or reflective surfaces can reflect infrared radiation, making it difficult for the NCIT to accurately measure the temperature of the target. In these cases, it may be necessary to use a NCIT with a higher measurement range or to place a non-reflective material between the NCIT and the target to improve accuracy.
Finally, be sure to follow the manufacturer's instructions for proper usage and care of the NCIT. This includes properly storing and handling the device, as well as replacing the battery as needed. Proper care will ensure that the NCIT continues to function accurately and reliably over time.
In summary, to properly use a NCIT and get an accurate reading, you should:
- Hold the NCIT correctly and aim the sensor at the center of the forehead or target area
- Calibrate the NCIT as needed
- Use the NCIT in a consistent, temperate environment
- Keep the NCIT clean
- Consider the distance between the NCIT and the target object
