The WH200D-1K / WH200D-2K / WH200D-3K Hot Plate is a heating plate with a
ceramic coated stainless steel top plate. It uses PID temperature control technology for
accurate and reliable results and is suitable for complicated temperature control
requirements. The LED screen can display both the set and actual temperature and the
value setting is easily done via a convenient on-touch control board. The Hot Plate
features a timer function for automatic heating of up to 100 hours and an alarm signal
and automatic stop function in case of over temperature situations. A PT100 temperature
sensor can be connected in order to provide direct and more precise control of the actual
temperature.
