RET control-visc

PATENTED WORLD FIRST: Safety magnetic stirrer with heating and integrated balance. Clear, multilingual TFT display makes it easy to set all parameters.
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. PT 100 temperature sensor is included. The stainless steel composite hot plate, reaching a temperature of 340 °C, enables rapid heating.
RS 232 and USB interfaces enable 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, the current temperature is displayed when the unit is switched off but surface is still hot. Below 50 °C the display turns off automatically.

• BNC socket for connection of a pH electrode
