Reach their max. temperature of 600 °C within about 20 min. The upper plate consists of titanium. Owing to a special insulation the device can be placed even on surfaces sensitive to heat. Metal sheets all around keep the casing temperature to a minimum. The insulated snap-lid ensures little loss of heat and short times of warming. Between the closed lid (inner surface Ceran^®) and the heating plate remain 26 mm*, enabling an intensive heating of plain parts at high precise temperatures. The whole casing is made of st. steel. The temperature regulator is connected by 2 plugged cables. PZ 28-3T is available either with a temperature contoller or with a programmer. The temperature controller keeps the device constant to an adjusted temperature within the whole range. The programmer allows the control of certain programmes incl. phases of heating up, constant temperature and cooling.
