The core component of an electronic thermometer is the NTC thermistors that measure temperature. For measuring body temperature, the accuracy, stability and sensitivity of the temperature sensor are required to be very high. Due to the high technical requirements for measurement accuracy, response speed, and annual resistance drift rate, about 70% of NTC thermistors in thermometers in China need to import from abroad. This is also a bottleneck problems for the industrialization of electronic thermometers in China. It has been reported that because of the influence of the technical level of domestic NTC manufacturers, the NTC temperature sensor used in China's electronic thermometers needs to be imported 100% from abroad, which is not accurate. Many domestic enterprises have already started special research and development in this area, and have begun to supply the finished products manufacturers of electronic thermometers. However, due to the limitation of the NTC thermistors technology level, the electronic thermometers produced by the company are not ideal in terms of temperature measurement accuracy, reaction speed and stability, and more or less different from actual temperature and temperature drift. In order to solve the problems in this domestic industry, Nanjing Shiheng Electronic Co., Ltd. Has researched since the beginning of 2006 to advance this technology. It has obtained 40 patents and developed a constant temperature oil tank with temperature control accuracy of 0.001 °C (ie 2 parts per thousand) for testing thermistors. After three years of technical research, at the end of 2008, we finally developed an NTC temperature sensor for electronic thermometers that is comparable to the world's leading NTC manufacturers.

The resolution of the sensor is up to ±0.01 °C, the accuracy is up to ±0.02 °C, the reaction speed is <2.8 seconds, the product stability is good, and the annual resistance drift rate is ≤0.1% (equivalent to less than 0.025 °C). Through repeated demonstrations by domestic and foreign users and testing by authoritative organizations, product performance has fully reached the level of advanced NTC manufacturers such as Japan. At present, this type of temperature sensor has achieved mass production and sales, with a monthly output of more than 3 million. In addition to providing support to domestic electronic thermometer manufacturers, it has also successfully exported to North America, South America, South Asia and other regions.
It can be predicted that environmentally-friendly electronic products, including electronic thermometers, will usher in a new era of rapid development.
