I have been using a Veridian touch-free infrared (forehead scan) thermometer for several years that I am very happy with. I use it for everyone as it is quick, keeps my hands farther away from their germs, and does not require costly probe covers; it is particularly helpful for students who don't like to be touched.
I was skeptical of the accuracy at first, so would take an oral with the Welch Allen Sure Temp Plus at the same time to compare, and found that they were consistently within 0.5 degrees of each other. In most cases, I find the Veridian identifies a fever before the Welch Allen if I monitor a borderline temp for 20-30 min. I still use the oral in some cases, such as when a student has just come in from outside in the winter.
Looking for input on best/effective practices, thermometers, and experiences on taking temperatures of students on the autism spectrum.
