Frequently Asked Questions About Thermometers

They are different measurement sites and can produce different readings. Use the site and technique specified for the selected thermometer and interpret the result in the appropriate clinical context rather than treating values from different sites as directly interchangeable.

A contact thermometer measures temperature through direct physical contact at the specified body site. An infrared thermometer estimates body temperature from infrared energy at the specified non-contact site, such as the forehead, using the method and distance stated in its current IFU.

No. Resolution or scale subdivision is the smallest displayed or marked increment. Accuracy is the allowed difference from a reference temperature under stated test conditions. A 0.1 degree display does not by itself prove plus/minus 0.1 degree accuracy.

A basal thermometer is used for consistent resting-temperature tracking. A sustained BBT rise may help indicate that ovulation has occurred, but BBT is not a stand-alone method for predicting ovulation in advance or diagnosing fertility problems.

BBT is generally more useful for identifying a sustained temperature rise associated with ovulation after it occurs than for predicting the exact ovulation time in advance. Illness, sleep, travel, alcohol, medication and inconsistent measurement timing can affect the pattern.

Follow the current supplied instructions and applicable infection-control policy. Do not assume boiling, autoclaving, immersion or a particular disinfectant is suitable unless the current IFU specifically permits that method.

The T15S listing is a digital contact thermometer, while the TP500 is a non-contact infrared thermometer. Exact T15S manufacturer/revision details and exact TP500 display/memory revision should be confirmed from the current supplied device and IFU for specification-controlled procurement.

Confirm the exact model/revision, measurement site, range, scale, documented accuracy, current IFU, filling medium where relevant, power or battery requirement, cleaning method, regulatory/conformity documentation, warranty, quantity and delivery destination.

Availability of mercury-containing medical measuring devices depends on current regulatory exemptions or restrictions, destination-country requirements, institutional procurement policy and the exact transaction. Buyers should request current availability and documentation instead of relying on older catalogue listings.
