Eco Temp Basic Digital Thermometer

Temperature ranges vary by age group. The following ranges are based on an oral measurement. The first group, babies and toddlers, ages 0 to 2 years range from 36.4°C – 38.0°C. Children age 3 to 10 years range from 36.1°C – 37.8°C. Young people and adults age 11 to 65 range from 35.9°C – 37.6°C, and adults over the age of 65 range from 35.8°C – 37.5°C.Please note that large individual variations are observed in groups of older people. Always consult with your healthcare professional for measurement methods and guidelines for reporting a fever.

Rectal:

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.

Ear:

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.

Oral:

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’.

Armpit:

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.

Battery: CR1220 lithium button battery (commercially available).
Use the battery within the recommended period indicated by its manufacturer. Replace the battery if the "low battery"and "A1" signs are on.
1) Remove the battery cover with a small cross-slot screwdriver.
2) Remove the battery with a thin object such as a pen.
3) Insert new battery with the “+” pole facing up as shown in the following figure.
4) Replace the battery cover and secure it with the screw.
