FEATURES OF CT915
●CT915 records measurement results automatically.
CT915 records data of up to 120 days (measurements).
●Basal body temperature recording mode or all-measurements recording mode can
be selected.
If the basal body temperature recording mode is selected, the temperature is recorded
only one time a day. If the all-measurements recording mode is selected, all the measure-
ment results are recorded.
●You can check the change of your body temperature by graph.
Since the temperature data of 31 days (31 measurements) is displayed by a graph, you
can also check the measurement result and date.
●Alarm to notify measurement time is available.
You can measure your body temperature at a regular time every day.
●You can take out and store the probe easily.
You can take out and store the probe easily since it is small in size.
●Antibacterial plastic is used.
An antibacterial plastic is used for the probe.
