REC has a white ceramic heating plate that is highly resistant to corrosion and excellent for observing changes of color (e.g. titrations, etc.) and that is extremely easy to clean. Micropocessor-controlled feed-back technology provides precise temperature up to 540°C and the bright red digital display visualizes always the temperature settings. Safety features include a "Hot Plate" digital warning system which is constantly displayed during operations when the temperature is above 50°C and flashes when the unit is switched-off until the temperature is cooled to below 50°C. The control panel that contains the electronic parts, is completely separate from the heating plate in order to increase the safety rating during use.
