cause hazards of explosion, implosion or release of toxic or
flammable gases from the material being heated.
Do not use in the presence of pressurized or sealed containers.
Fire or explosion may result causing injury or death
Do not operate the plate with external temperature probe
in the air or out of the liquid.
The external probe must be properly placed into a liquid
on the top surface during the whole process, to prevent
damage to the plate
