Precision Hot Plates for non-stop operation


The heating surfaces of the precision hot plates are composed of an efficient heat conducting Aluminium alloy, and have a smooth anodised finish for easy maintenance. The electrical long-term heating ensures that the temperature remains constant, even on the corners and edges.
The microprocessor controlled digital regulator allows the operating temperature to be preset in 0.1°C stages up to 99,9°C and in 1.0°C stages for temperatures over 100°C. The preset temperature remains programmed, even when the equipment has been switched off. Presetting is only possible by using two fingers; this is to prevent any unintentional alterations that could occur by accidentally touching only one key. The actual temperature is
permanently displayed by 14mm high numerals after the keys have been released.

An adjustable safety device against overheating prevents the hotplate and the substance to be heated, from dangerously high temperatures. A removable Plexiglass cover prevents any unauthorised adjustments. All models have an electronic output control that allows the heating output to be adjusted between 10..100%, this prevents the hotplate exceeding the preset temperature and/or avoids any after-heating. The temperature of all hotplates is
measured with a built-in, quick-reaction sensor (PT 100). All models are equipped with a 3-pole diode output bushing (extra-low voltage), to permit the connection of one of the 
following appliances:

  1. Contact Thermometer – to measure the temperature directly from the heated material and to regulate.
  2. Time switch – in order to heat or cool the apparatus at preset intervals.
    Model PZ 60 (long shape) is equipped with 5 screw-in sockets for support rods, at intervals of 125 mm.

Special Feature:
Due to the asymmetrical, quick-reaction special heating and thermal sensors as well as output adaptation to the thermal requirements, very precise temperatures with a good uniform heat are obtainable over the whole heating surface.
