PZ 28-1 ET Precision Hot Plates
Precision Hot Plates for continuous operation
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.
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.

The microprocessor controlled ramp regulator PR 5 SR is a complex time/temperature control for the precisionhotplates. Pressing the START key enables the programming of a set of a maximum of 5 ramps (each ramp consists of the ramp-time, constant temperature and the duration of the constant temperature). 3 programme sets can be stored in the non-volatile
memory bank.
Further Advantages:
¸ A programmed lead time enables the start to be activated up to 99 hours in advance.
¸ Easy and comprehensible programming because each temperature and time parameter has its own key. At any time during the running of the programme it is possible to check each programmed value.
¸ Output regulator from 0-100%
¸ Change-over switch for non-stop operation.
¸ Programme back-up by EEProm.
¸Buzzer signal at the end of the programme.
