A fever is one of the leading symptoms of COVID-19 and other illnesses during the cold and flu season. It is important to know your temperature before you go out in public. COVID-19 has brought and will continue to bring significant changes to the way businesses are run after reopening. It is becoming more common for businesses to conduct mandatory employee temperature checks. This calls for a new need: businesses need many people’s temperatures checked in a short amount of time. Accuracy and efficiency are two very important factors to consider when choosing which thermometer to use at your business. Many businesses prefer to use an NCIT to measure employees’ temperature. NCITs are more efficient for business because they give fast readings that allow employees to be tested quickly. They don't need to be cleaned after each use, allowing many people to be checked in minutes. Oral temperatures, on the other hand, take longer because the thermometer must be cleaned, and they don’t always give instant readings. The no-contact option keeps employees safer and prevents the spread of germs if an employee is sick. Businesses find it worth it to use an NCIT despite it being less accurate because of the efficiency and cleanliness. At home, a regular digital thermometer is most accurate.
