4. How This Thermometer Measures
Temperature
This thermometer measures infrared energy radiated from the eardrum and the
surrounding tissue. This energy is collected through the lens and converted to
a temperature value. The measured reading obtained directly from the eardrum
(Tympanic Membrane) ensures the most accurate ear temperature.
Measurements taken from the surrounding tissue of the ear canal generate
lower readings and may result in misdiagnosis of fever.

13. Care And Cleaning
Use an alcohol swab or cotton tissue moistened with alcohol (70% Isopropyl)
to clean and disinfect the thermometer casing and the measuring probe.
Ensure that no liquid enters the interior of the thermometer. Never use abrasive
cleaning agents, thinners, or benzene for cleaning and never immerse the
instrument in water or other cleaning liquids. Take care not to scratch the
surface of the probe lens and the display.
It is important to clean the thermometer before and after each use. A build up
of ear wax on the lens reduces the infrared picked up by the sensor, which can
result in lower temperatures. Ear wax is also acidic and can corrode the lens of
the thermometer if not cleaned regularly.
