In current market, there is an active demand for high stability, high precision and high heat-resistance NTC thermistor, such as thermistor for measuring exhaust gas for automobile. The working temperature is 400-500°C. For liquefied petroleum gas temperature measurement, the temperature is rather high too. Therefore, the need for high temp. thermistor is very urgent. Mn-Co-No series thermistor temperature is about 300°C. In order to increase the working temperature, there are some experiments for high temp. thermistor by addingZrO₂, Cr₂O₃ and Al₂O₃.

High temp. thermistor can be used in business automation equipment, high speed printer hothead, for measurement of 100°C and above. For NTC thermistor used in automobile, air conditioner and air heater, high response speed and high precision are needed (resistance error is ±1%). Household water heater, electric rice cooker, glass encapsulated NTC thermistor can be used. Based on many experiment results, by using thermistors in the electric devices, products have much better performance.

With the development of electronic industry and the improvement of people's living, there are more and more demands for electronic products, especially for the products related to electronic temperature control. Due to the demands for accurate, compact and light products, mechanical temperature control shows increasingly limit, so high precision NTC thermistor, as the key temperature measurement component,  becomes more popular thanks to its compact size, high precision and wide working temperature range.
