The Solomon Infrared Ear Thermometer is available with a short tube with a protective sleeve which is inserted into the ear and a shutter is opened to allow radiation from the tympanic membrane to fall on an infrared detector for a period which is typically from 0.1 to 0.3 seconds in the varieties surveyed
The device beeps when data collection is completed and a readout of temperature is produced on a liquid crystal display
This kind of temperature from the eardrum has been found to be a clinically reliable indicator of body core temperature
The eardrum is located close to the hypothalamus, which is the body temperature regulator
The membrane itself is thin and almost transparent in the visible, so you would presume that it reliably tracks the temperature inside the membrane so that the infrared energy it emits gives a good indication of the inside temperature
The infrared energy falls on a thin pyroelectric crystal which develops a charge proportional to that collected energy
Discharging the crystal sends a current pulse through filters and conversion circuits which compare the signal to tabulated data on temperature and calculate a body temperature for the display
How to use: ◦ Please use a new and clean probe cover for every measurement ◦ Please read through the instruction manual before using the thermometer; as proper technique is critical for taking accurate temperatures ◦ The performance of the thermometer may be adversely affected with improper usage ◦ Do not use the thermometer outside the operating ambient temperature of 10 ° C (50 ° F)~4 ° C(104 ° F) ◦ Do not use the thermometer outside the operating ambient humidity up to 95%RH ◦ Do not use the thermometer when the ear canal is wet or when the person is suffering from ear diseases ◦ Earwax and obstructions will affect the accuracy of the thermometer ◦ Side way sleeping gesture will cause the ear temperature to rise; please avoid it ◦ The thermometer is calibrated and does not require re-calibration if used according to the instructions
Thermometers are used to measure fever in humans or tell you how cold it is outside. Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is straightforward. Thermometers measure temperatures in degrees, according to either the Celsius or Fahrenheit system
Digital thermometers are temperature-sensing instruments that are easily portable, have permanent probes, and is equipped with a convenient digital display. The way a digital thermometer works depends upon its type of sensor. Sensor types include resistance temperature detector (RTD), thermocouple and thermistor.
One can use any thermometer, with mouth open, put the end with the red, blue, or silver-coloured tip under your tongue. Close your lips gently around the thermometer. Do not bite the glass thermometer.
Cleaning of the thermometer is also important. It's important to clean the thermometer after each use, but how you clean it depends on what type of thermometer you have. For glass thermometers, wash it with soap and cool water, then rinse and dry. For digital thermometer you can wipe it with a cloth soaked in alcohol or water. Allow it to air dry
