Advantages of the thermometer
Two measurement methods: measurement from ear and forehead
1. Thermometer measures body temperature (Body Temp mode) from ear and forehead.
Depending on what you prefer, you can choose a place for temperature measurement.
2. The thermometer also measures the surface temperature of objects (Surface mode).
High measurement accuracy with the latest measurement sensor technology the latest
generation of measurement sensors guarantees a very high accuracy of temperature
measurement when measured from ear and forehead.
When measuring the temperature of objects, the thermometer only needs to focus on the
desired object.
Due to infrared technology is very fast.
The measuring sensor captures the infrared radiation emanating from the drum,
respectively. from the face of the forehead and report the measurement result at a time.
Simple operation
The instrument is operated very easily and safely with the buttons. Use the power button
(memory data recall) to turn the device on or off and also to start the measurement.
Principle of operation
Each object produces a certain amount of energy of infrared radiation. The energy of the
radiation emitted and its wavelength depends on the surface temperature. The human body
at a temperature in the range of 35.5 - 43.0 ° C emits infrared rays with a wavelength of
5 - 13 μm. Based on this fact, we can accurately calculate the body temperature from the
difference between body temperature and temperature at the face surface.
Advantages of the thermometer
The thermometer measures Body Temperature from ear or forehead. Depending on what
you prefer, you can choose a place to measure body temperature.
General body temperature information
The human body regulates the body temperature to the desired value - it is up to 1 °C
throughout the day. The temperature in the body (core body temperature) and surface
temperature on the skin show different values. So there really is no “normal” body
temperature - it always depends on
measurement site. Body temperature is also affected by external temperature, age, stress,
sleep time, hormones and physical activity. While the classic glass thermometer and digital
thermometer directly measure body temperature, measurement of body core temperature
through infrared radiation of the body is measured in the ear and forehead. This can also
differ slightly from the temperature measured in the rectum, the oral cavity, or in the armpit
with a digital thermometer even if measured correctly.
During life, the average body temperature can fall by up to 0.5 °C.
Overview of measured values (°C):
Status Ear/Face
Low temperature < 35,7
Normal temperature 35,8 – 36,9
Increased temperature 37,0 – 37,5
Light Fever 37,6 – 38,0
Mild fever 38,1 – 38,5
High Fever 38,6 – 39,4
Very high fever 39,5 – 42,0
• The temperature measured in the ear may differ from the temperature measured on
the forehead as the face temperature affects the external influences more than the
temperature of the ear drum.
• The same is true when compared to measuring body temperature in the rectum, the oral
cavity, or the armpit.
• Repeated measurements of consecutive measurements generally have slightly different
results, however, they move within the tolerance of the measurement.
