If you want to use what your doctors use, this is the one for you. The Welch Allyn Temp Plus is a large, two-piece thermometer with a removable probe. You are guaranteed a quick and accurate reading on its easy to read large LCD display screen. The thermometer is also equipped with 60 second timer to measure pulse and respirations. Unfortunately, with a big price tag and a limited warranty, you can find many of the same features on a less expensive model and use this one when you visit your doctor.
