A thermometer is a medical device that helps you take the temperature of your core, which is the temperature of your heart, brain, and other organs. OMRON offers you a range of accurate and reliable in-ear, infrared (contactless), and pencil/stick thermometers.
Ear thermometers’ accuracy is high because they can detect the infrared heat given off by the ear drum, providing you precise results. They must be used with probe covers on, but if it gets dirty, you can clean it with an alcohol cotton wet cloth. However, Infrared thermometers are a great option for a fast, contactless reading.
Forehead thermometers can give you accurate results in just 1 second, and they can measure surface temperature, as well as a drink bottle temperature, such as a milk bottle for your baby. How to use an OMRON forehead thermometer? Simply place the thermometer from 1 to 3 cm away from the body part or object to be measured, and press the start button. The result will appear automatically on the screen.
A new probe cover must be used for each measurement in order to ensure accurate results. Never use the thermometer without a probe cover as this can cause the lens to become dirty and potentially impact the accuracy of the temperature measurement. The Probe Cover is critical to ensure fingerprints, ear wax or dirt will not contaminate the probe and impede upon the accuracy of the thermometer. If the probe lens becomes dirty it may be gently cleaned with a soft cotton cloth moistened with alcohol. Do NOT use a paper towel. The fibers in the paper towel may scratch the probe lens. Allow forty- five (45) minutes for the probe lens to dry completely before attaching the Probe Cover. Always return the thermometer to its protective case when not in use.
The most reliable core temperature is obtained by inserting a thermometer into the rectum (rectal measurement). This measurement is accurate and has low possibility for errors in the results. The normal range is approximately: 36.2°C – 37.7°C.
This is also a very reliable method of measuring core temperature. In this case a thermometer capable of detecting the infrared heat given off by the ear drum (tympanic membrane) is used. This measurement is accurate and has low possibility for errors in the results. The normal range is approximately: 35.5°C - 37.5°C.
The oral measurement can be performed as ‘in the cheek’ measurement (called buccal) or as a ‘under the tongue’ measurement (called sublingual). Both measurements underestimate the rectal temperature by approximately 0.3° C – 0.8° C, with the ‘under the tongue’ measurement being preferable to ‘in the cheek’.
Body surface temperature measurements used in clinical practice are in the arm pit (axillary measurement) and in the groin. In both cases the respective limb is pressed against the body in order to reduce any ambient temperature influence. However, this is successful only to a limited extent with the disadvantage that the measurement time is long. In adults, the axillary measurement is lower than the rectal by as much as 0.5°C – 1.5°C! In infants, these differences, in comparison with the rectal temperature, are much smaller.
