1. The device is useful in various ways that the sheet passes through heated drum and felt for smooth drying. 2. The dryers surface temperature loss is not high enough that the consecutive drying or the drying the high humid sample does not cause any problems. 3. The same felt as the paper manufacturing is used to increase the reproducibility. Features:1. The rapid increase in temperature shortens preheating time. 2. The digital adjustment in the temperature and speed results in a more precise experimentation. 3. The surface of the dryer has been processed with the special substance for contamination-proof and easy cleaning features. Spec: Digital Display & digital temp.
