The following introduces methods for measuring the temperature of high-temperature graphite furnaces, which we hope will help our customers.
Although the temperatures inside the core of Dingsheng high-temperature graphite furnaces vary considerably, in industrial production, measuring the exact temperature of every furnace is generally impractical. Therefore, furnace temperature is mainly controlled indirectly through input power, power ramp-up, and total energy consumption.
However, for experimental purposes—such as testing the power curve, understanding the core temperature distribution, or studying temperature behavior—direct measurement may be required.
- For graphite furnace cores below 1600 °C, thermocouples combined with automatic balanced recorders can be used.
- For temperatures above 1600 °C, optical pyrometers or photoelectric high-temperature meters are used. These instruments typically have a maximum measurement range of up to 3200 °C, approximately double the lower range.
