Heating; Set Temperature - Heidolph MR Hei-Standard Betriebsanleitung

Operation

Heating



Set temperature

Warning:
Risk of burning!
The hotplate can reach temperatures up to 300 °C.
If you work with temperatures above 50 °C wear safety gloves and
appropriate protective clothing.
Warning:
Risk of ignition!
Infl ammable samples may ignite with high temperatures.
If you work with infl ammable samples set temperature at least
25 °C lower than ignition point of sample.
There are two options to control heating:
▪ Without external temperature sensor: temperature will be measured and controlled
via hotplate.
▪ With external temperature sensor: temperature will be measured and controlled via
sensor directly in sample (see chapter "Assembly, Temperature sensor").
You can set the following temperature range:
▪ Hotplate / temperature sensor: between 20 °C and 300 °C (lower degrees depending
on ambient temperature).
Working without external temperature sensor:
Due to differences in heat conductivity of various materials of vessels
and sample the temperature of hotplate should be set 1½ to 4 times
higher than the desired sample temperature.
