1. The relationship between the selection of the temperature range of the hot air circulation oven and the use temperature When the use temperature is below 290 ℃, it is recommended to choose an oven with a temperature range of RT + 10 ~ 300 ℃; Use a high temperature oven (drying oven) at 500 ℃; when using temperature between 450 ℃ ~ 560 ℃, choose a high temperature oven at 600 ℃
2. The temperature uniformity of the hot air circulation oven is an important performance. It is also an important indicator for judging the quality of an oven. In the constant temperature stage of the oven, although the temperature of the control instrument is generally stable, the temperature of each point in the oven is different, which will cause the samples at different locations to be heated differently. Hope these suggestions are helpful to everyone.
