Taking an out-of-line electronic thermometer as an example:
It means that this electronic thermometer has begun to be able to measure body temperature.
Some electronic thermometers will be in Chinese, some will be in English.
1, structure: temperature sensing head, temperature measuring stick, display, switch button and battery cover.
2, electronic thermometer temperature measurement principle:
Electronic thermometer is the use of temperature sensors to output electrical signals, and then the current signal is converted into a liquid crystal digital display of the temperature, as well as the ability to maintain the highest value of the temperature being measured.
3, electronic thermometer is the most core components of the temperature sensing NTC temperature sensor. Sensor resolution up to ± 0.01 ℃, accuracy up to ± 0.02 ℃, response speed & lt; 2.8 seconds, resistance annual drift rate of ≤ 0.1% (equivalent to less than 0.025 ℃).
Expanded Information:
Infrared thermometer use:
Forehead touching .
In the use of non-contact infrared thermometer on the same person to measure, pay attention to keep the distance between the thermometer and forehead 5 to 15 centimeters (pay attention to move away from any obstacles that may affect the measurement, such as hair, sweat, etc.), if you get the same temperature of 37.5C (99.5F), it means that the non-contact infrared thermometer can be used.
Infrared thermometer notes:
1, the use of the process, some friends will say that the measurement results have a deviation value, in fact, the infrared thermometer is affected by external factors, it is recommended that we measure at the usual room temperature.
If it is in an air-conditioned house, the temperature of the environment itself is 36 degrees, then the human body for a long time in an air-conditioned house, the measurement of the object table will be greatly affected. Also be careful to avoid measuring in an environment where the temperature is higher than the daily temperature or lower than the daily temperature.
2, the process of using the product will have a 0.3 deviation value, 0.3 deviation value for most consumers can accept.
Compared with the traditional thermometer, now the baby's not likely to be obedient to measure with the traditional thermometer, they see these glass thermometers will have a sense of fear, if you want them to measure the temperature of at least ten minutes, coupled with the babies are always moving around, the measurement of the temperature deviation will be even more inaccurate.
It is recommended that friends in the process of measuring the measurement distance as far as possible to maintain in 3 to 5 centimeters, too close or too far away from the distance will affect the results of the measurement of the value. In the measurement of this will also have some reference values, consumers can be based on the reference value to consider the value, or can be measured at intervals to see the time, a few more measurements, and then determine the temperature change.
