Digital 7” Square(Hotplate)Magnetic Stirrer
Manufacture’s standard accessory. If the sensor is not
plugged in,“Probe”will flash. If plugged in,“Probe”
will be shown on the digital display to indicate the sensor is
operating. The setting value of external temperature sensors
and actual temperature are displayed. Safe circuit controls
hotplate temperature.
Comparing with the temperature control of the hotplate,
the external temperature sensor can control the medium’s
temperature more precisely.
Warning！
Do not insert or remove sensor while heating.
7.2 Residual heat warning (Hot)
In order to prevent the risk of burns from a hotplate, digital
hotplate model has a residual heat warning function.
When the heating function is switched off and the hotplate
temperature is still above 50℃,“Hot”will flash to warn
that there is a hazard of burns from the hotplate (Figure
6).When the hotplate temperature drops to below 50℃, the
unit will automatically switch off. If users want to turn off
the LCD immediately, just pull out the plug directly. When
the plug is pulled out, the residual heat warning function can
not be run.
case, set the heating temperature display the actual
temperature may have the following differences:.
- Hotplate center and outer edge.
- The sample container and the container.
In order to ensure the accuracy of the temperature inside
the container, please use the external temperature sensor
PT1000.
