Pros and cons
The infrared thermometer has the advantages of convenient, simple, fast and accurate temperature collection, which
is very suitable for patients with severe illness, the elderly, infants and young children. The disadvantage is
that it is susceptible to ambient temperature, and the error is large in this case.
