Wagen Preditive Basal Thermometer and 50 Ovulation Test Strips, Ovulation Predictor Kit for Natural Pregnancy

Description

What are the difference between a regular thermometer and a basal thermometer?
A regular thermometer for fever diagnosis takes temp in 1~3 minutes. As the body temperature shifts by time, 1~3 minutes is need for fever diagnosis to go over a circle and get temperature crests. It requires less sensitive (digital one ±0.1C, mercury one ±0.2C).
A basal thermometer for basal body thermometer (BBT) charting needs to be more sensitive to ±0.05C, so it can detect the 0.2~0.5C temp rise before and after ovulation. It d better read fast, since BBT is easily affected by activities after awaken. Wagen is professional in BBT charting for it is accurate, sensitive and fast reading.

Why I got different readings in back to back measurements?
In people s common sense, we should get consistent readings in back to back tests. However, the body temperature is not a fixed number but a waveform curve with peaks and valleys shifting by time. The lowest temp (as we call Basal Body Temperature) attains usually during sleep, while the highest temp attains usually at noon. Even a man is calm, his body temp shifts in a small range. The fact is that, we get consistent readings in back to back tests of every 3 minutes, we probably not in back to back tests of every 9 seconds. The key is time. Is it long enough to go over a circle with temperature peaks.
As to Wagen, it has [Actual Mode], [Predict Mode] and [Persistent Measure Mode]. You are supposed to get different readings in back to back tests under [Actual Mode] and [Predict Mode], b/c it is sensitive enough to tell the slight difference of every 9 seconds. Keep measuring after it reads, it will enter [Persistent Measure Mode]. Here it measures as long as 10 minutes, and you can get no doubt consistent readings.
