1. Temperature measurement range: generally 32 ℃ to 42 ℃ (89.6 ° F to 107.6 ° F).
2. Accuracy: Temperature error should be less than or equal to plus or minus 0.1°C.
3. Response Time: Measurement time should not exceed 1 minute.
4. Repeatability: in the same environment, the error of repeated measurements should not exceed 0.1 ℃.
5. Storage temperature: generally should be stored in the range of -20℃ to +70℃.
6. Ambient temperature: the thermometer should be used in an ambient temperature within the range of +10℃ to +40℃.
To ensure the reliability and accuracy of the thermometer, it is necessary to follow the instructions. Generally speaking, there are several ways to measure body temperature:
1. Underarm temperature measurement: put the probe of the electronic thermometer into the armpit, close to the skin, do not move until the "drop" sound, indicating that the measurement is complete.
2. Oral thermometry: put the probe of the electronic thermometer into the lower side of the tongue, close to the tongue, and keep it still until the "drip" sound, indicating that the measurement is complete.
3. Anal thermometry: Apply lubricant, insert the probe of the electronic thermometer slowly into the anus until it is fully inserted, and keep it still until the "drip" sound indicates that the measurement is complete.
4. Ear canal temperature measurement: put the probe of the electronic thermometer into the ear, gently press the measurement button, and keep it still until the "drip" sound, indicating that the measurement is complete.
In short, the use of electronic thermometers need to follow the requirements of the manual to operate, choose the appropriate measurement position, to maintain the stability and accuracy of the measurement.
