3. Advantages of the thermometer
Two measurement methods - ear and forehead tempera-
ture measurement
Veroval
®
DS 22 measures temperature in the ear and on the
forehead. Select between the two modes according to your
preference. You can set it to take either ear or forehead tem-
perature readings by using the mode switch on the side of the
thermometer.
Rapid measurement using infrared technology
The measuring sensor records the infrared radiation emitted
from the eardrum or the surface of the forehead and after one
second displays the measurement result for ear temperature
measurement and at the end of the scanning process it dis-
plays the highest measurement result that was detected for
forehead temperature measurement.
Robust and reliable through high quality of workman-
ship
This device has been developed in accordance with the
HARTMANN quality assurance guidelines. Designed to meet
customer needs, it meets high stability standards.
4. General information on body
temperature
The human body regulates the body temperature to a target
value and it can fluctuate by up to 1°C over the course of
a day. Throughout the course of life, your average body
temperature can decrease by up to 0.5°C. Moreover, the tem-
perature inside the body (core temperature) and the surface
temperature on the skin have different values. Body tempe-
rature measured in the ear or on the forehead can produce a
reading that is different from an oral, rectal or axillary tempe-
rature measurement. It therefore makes no sense to compare
those values. Measuring a temperature in the ear and on the
forehead can provide results that differ because the forehead
temperature depends more on external influences than the
temperature of the eardrum.
In addition, forehead temperature is also more dependent on
external influences than rectal, oral or axillary temperature
measurement.
