and temperature display. Three power levels (825, 1650 and 3300 W) can be set and an
additional electronic power controller (adjustable 10 to 100 %) is provided.
At 825 and 3300 W settings the entire plate surface is heated.
At 1650 W setting only the right hand side of the plate is heated. As a result of heat conduction, the temperature
from the right hand side to the left edge of the plate varies by approx. 40%.
With solid, flat, low-distortion, cast GG15 alloy.
