Using bimetallic thermometer easy, invented it?

As we all know, the thermometer has great effect on medicine. So now that the bimetallic thermometer in my life we use plays such an important role, that we all know who invented the thermometer? With only small changes in the temperature in the human is unable to accurately said, in order to determine the now ordinary thermometer on each scale, the original is hot and cold by the feeling of people conjecture, we know that use an object may only need to learn the time of day, but the inventor invented the thermometer took about one thousand years. The first practical thermometer is in the world by the German move warren hite instrument manufacturers in the Netherlands in 1709 began to make alcohol thermometer readings is consistent, the need of the doctor are proposed in order to see the doctor, the best points of the four levels to represent the changes of cold and hot. Calais suggest four grades of hot or cold is not the temperature of the thermometer before labeling, this is not surprising that the temperature of the quasi equilibrium, before the 17th century, has been adopted by the medical profession. Take the temperature and humidity recorder, we compared the commonly used measuring instrument is now. When people live is not very delicate, a rough description can barely cope with people getting to know the needs of the changes in temperature, but different about scientific research said, it needs to be accurate temperature measurement. Till now, may be more and more, the kinds of bimetallic thermometer regardless of how we should not forget our convenient actually comes from many previous efforts, their efforts to benefit our future generations. Is the contribution of scientists, let us now use more and more convenient, no matter how, we all should continue to strive for scientific innovation.
