For that you need an accurate thermometer. And accurate equals slow and steady. Especially when you measure orally. Conclusion: we had to make a thermometer that can handle oral measurement and still does a great job in accuracy. So we did! But why does an accurate oral thermometer need to be slow? Well, let me explain. If you keep your mouth open and breath in, the air flowing through your mouth is cooling down your mouth tissue. 0.2-0.5 degrees is usually not much of an issue unless...you are charting for ovulation. You want to know the 0.02 differences! For that we modified our algorithm to come as close as possible under the tongue. That takes time. Speed is an accuracy killer in this case. Sounds complicated? It is. But we try to help you understand that oral measurement is not the best way to go for charting unless you do it RIGHT: Sit tight, mouth shut and don't move.
