November 27th, has bought 2 home thermometer, the temperature of the 2 figures are almost the same. But I personally feel wrong, because it is very hot or very cold when it is 21 degrees -24 degrees floating. For example, it is now very cold, I wear a thick coat, the thermometer is still 21.3 degrees, but I see the Baidu weather forecast is 10 degrees.What is the reason??? Is not the thermometer is crooked goods, I 2 thermometers, one is bought by Taobao, a supermarket to buy
People feel the hot and cold with the temperature have a certain relationship, but not necessarily (for example, the same is the case of 15 degrees, the hair on the feeling very cold, do not blow on the top of the Shun)
There is a temperature difference between indoor and outdoor;Indoor thermometer to get the outdoor test, there is a delay, 10 minutes or so to measure the true value
The measurement tool on the market without correction, how many of them are not accurate, the accuracy and sensitivity of the thermometer is basically to be proportional to the price of kerosene thermometer, mercury thermometer, you should determine who is good, there are some sort of electronic thermometer, the accuracy is poor.
