Which brand is better, the electric muffle furnace or the high-temperature furnace, with high cost performance and no error, and the operating temperature is 600 degrees. Please recommend it.

It's hard to say which brand is better, the electric muffle furnace or the high temperature furnace. Our laboratory has an energy-saving optical fiber resistance furnace SX3- 1.5- 10 of Hangzhou Zhuochi Instrument Co., Ltd., which has no error when used at 600 degrees, 800 degrees and 1000 degrees, and the temperature rises rapidly, reaching 1000 minutes. The error of the other two brands' high temperature furnaces is about 10 degrees (also within the national standard).
