A non-contact thermometer is a device used to measure temperature without direct contact with the object or person. It typically uses infrared technology to detect the heat emitted from a surface, providing quick and accurate readings. These thermometers are commonly used in medical settings to check body temperature, especially during health screenings. Non-contact thermometers are also useful in various industries, such as food safety and HVAC systems, where monitoring surface temperatures is essential. They are easy to use, often featuring a digital display for clear readings, and are designed to minimize the risk of cross-contamination, making them ideal for public health situations.
