Stuart CR300 - Hotplate, Infra Red, 230V

Using a very efficient infra red heater of just 900W power this hotplate will boil 1 litre of water over 30% faster than a conventional ceramic hotplate of 1200W. Ideal for heating large volumes of liquid.

Heating

Models SB300, SB302, SB500, CB300, CB302, CB500:

The knob labelled “Heat” on the front panel controls the heat output and hence the plate temperature.

The knob is graduated from 1 - 9. Increasing the value increases the heat output.

Turn the hotplate control knob clockwise to the desired setting. The amber load indicator light will illuminate and it will begin to cycle on and off when the desired temperature is reached and the hotplate begins to control.

Models SD300 and SD500:

When connected to the mains electricity supply the digital display will illuminate and show the word OFF.

Stirring

Models SB301, SB302, CB302 and CR302:

The knob labelled “Stir” on the front panel controls the stirrer speed. 

It is labelled with an arbitrary numeric scale, 1 - 9 and turning the knob to a higher setting increases stirrer speed.

When the stirrer is switched on the amber pilot light illuminates.

Models CR300 and CR302:

The knob labelled “Heat” on the front panel controls the heat output and hence the plate temperature. When the heat is switched on the amber pilot light illuminates.

The knob is graduated from 1 - 9. Increasing the value increases the heat output.

In operation only the area defined by the pattern will become fully heated. The outer edges remain cooler for safety considerations. 

Vessels larger than the described area should not be used. Failure to observe this could give rise to overheating of the outer parts of the instrument.
