Armpit temperatures are usually the least accurate. The average normal oral temperature is 986f 37c.

Types of body temperature measurement. Body temperature readings vary depending on where on the body a person takes the measurements. Rectal temperatures provide the best readings for infants especially those 3 months or younger as well as children up to age 3. A thermometer is an instrument that measures temperature. Taking a rectal measurement is the most reliable way to obtain a core temperature value. The seven basic types of temperature measurement sensors discussed here are thermocouples resistive temperature devices rtds thermistors infrared radiators bimetallic devices liquid expansion devices molecular change of state and silicon diodes. Rectal readings are higher than oral readings while armpit readings tend to be lower.
The normal body temperature when measured orally should show 986 degrees fahrenheit. There are various types of medical thermometers as well as sites used for measurement including. These measurements are most commonly used as a reference standard. This type of measurement can be slightly more inconvenient as compared to the oral measurement. The exact relationship between different types of temperature measurement is unclear. Peripheral ports 1 dc port 1 rj45 1 micro usb 1 wiegand 1 rs485 audio digital audio speaker microphone.
Body temperature measurement precision03 best use distance 05m 07m. In the rectum rectal temperature in the mouth oral temperature under the arm axillary temperature in the ear tympanic temperature on the skin of the forehead over the temporal artery. Regular digital thermometers use electronic heat sensors to record body temperature. Result variation with this type of measurement is low and the precision is particularly high. A rectal temperature is 05f 03c to 1f 06c higher than an oral temperature. The readings obtained from this technique are fairly inaccurate.
These thermometers can be used in the rectum mouth or armpit. The normal temperature range is approximately between 366 c and 380 c. However the following general guidelines for temperature results are used. Some temporal thermometers work through rolling the scanner over the forehead calculating the temperature based on the heat detected. Forehead or temporal thermometers take a temperature reading through an infrared scan of the temporal artery in the forehead.
