Infrared temperature measurement technology has advanced to scan surfaces with thermal variations, determining their temperature distribution patterns and swiftly detecting hidden temperature differences—this is the infrared thermal imager. Initially deployed for military applications, Texas Instruments (TI) developed the world's first infrared scanning reconnaissance system in 1960.Subsequently, infrared thermal imaging technology was progressively integrated into aircraft, tanks, warships, and other weaponry in Western nations as thermal targeting systems for reconnaissance, significantly enhancing search and target acquisition capabilities. Swedish AGA Corporation's infrared thermal imagers lead the field in civilian technology. However, how to achieve widespread application of infrared temperature measurement technology remains a worthwhile research topic.
Three Major Categories of Infrared Thermometers
1. Personal Infrared Thermometers
2. Industrial Infrared Thermometers
3. Dual-Color Infrared Thermometers
Usage of Personal Infrared Thermometers:
Pre-First-Use Advisory: To obtain stable and reliable temperature readings, perform the following checks before using a non-contact infrared thermometer:
Step 1: Measure the same person's temperature using a traditional thermometer. Assume a reading of 37.5°C (99.5°F).
Step 2: Measure the same person using the non-contact infrared thermometer, maintaining a distance of 5 to 15 cm between the thermometer and the forehead (ensure no obstructions like hair or sweat interfere with the measurement). If the same temperature of 37.5°C (99.5°F) is obtained, the non-contact infrared thermometer is ready for use.
If a lower reading is obtained, such as 36.4°C (a 1.1°C difference), you need to calibrate the non-contact infrared thermometer by adding the difference.
To do this: Press and hold the "MODE" button for two seconds until the screen displays F1. Press "MODE" again to directly enter F3, then press the "UP" button to add the difference.
Step 3: Re-measure to verify.
