                                    Cost-effective, universal laboratory stirrer for simple stirring tasks up to 20 litres (H2O). An electronic safety circuit guarantees that the appliance is switched off in the event of a fault or overload. Microprocessor control continuously synchronises set and actual speed. This means that the speed remains constant even if the viscosity of the medium changes.Brushless, maintenance-free motorRobust housingDigital display of speed and torqueInfinitely adjustable speedOverload protectionNon-slip matQuick-release chuck enables simple stirrer shaft change without toolsSilicone cover protects drill chuck and motor from erosive vapours and splashesRS232 interfaceScope of supply: Overhead stirrer, stand, non-slip mat, 4-blade propeller stirrer
