RET control-visc safety magnetic stirrers with heating and integrated balance which are suitable for unsupervised operation. Clear, multilingual TFT display makes it easy to set all parameters and the sealed casing ensures a long service life. Integrated temperature control feature enables connection of a temperature probe, placed directly in the medium, to control medium temperature with a high degree of precision. The stainless steel composite hot plate (white units have a chemically resistant enamelled plate), reaches a temperature of 340 °C, enabling rapid heating. RS232 and USB interface enables PC control of the magnetic stirrer and documentation of all test parameters. 'Lock' function prevents inadvertent changes of speed and temperature settings. As a safety feature, a 'hot' sign flashes when the unit is switched off but the heating surface is still hot. Unit has a DIN 12878 socket for connecting an electronic contact thermometer, for high precision temperature control and also features detached magnet detection and has a BNC socket for a pH electrode.
