近年来,由于农村经济政策的落实,大大激发了生产的积极性,另外由于推广科学种田,使粮食的产量大大增加,因而需要储存的粮食也增多了。过去,有些地区对粮仓保管不善,粮食变质之事常有发生,有的地区每年变质粮食。就有几亿斤之多,不能有效进行温度监测就是一个重要原因。我国大部分地区仍采用人工操作,既费工又费时,而且测量不准确。因此,使用单位迫切要求能够采用自动测量、价格低廉的粮仓测温仪。由于粮仓所在地区气温不 In recent years, due to the implementation of rural economic policies, the enthusiasm for production has been greatly stimulated. In addition, due to the promotion of scientific farming, the output of food has greatly increased, and the amount of food that needs to be stored has also increased. In the past, grain storage was not good enough in some areas, and grain deterioration often occurred. In some areas, grain was spoiled every year. There are hundreds of millions of jin and can not effectively carry out temperature monitoring is an important reason. Most parts of China still use manual operation, both labor-intensive and time-consuming, and the measurement is not accurate. Therefore, the use of units urgently require the use of automatic measurement, inexpensive granary thermometer. Because of the temperature in the area where granary is not
