Extremely powerful laboratory stirrer for highly viscous applications and intensive mixing for quantities up to 100 l (H2O). It automatically adjusts the speed through microprocessor controlled technology within the speed range of 0/6 – 2000 rpm (two speed ranges). Safety circuits installed ensures automatic cut-off in an anti-stall or overload conditions. Continuous comparison of shaft speed to desired speed is maintained and variations are adjusted automatically. This guarantees a constant speed even with changes in viscosities of the sample. • Digital speed display • Infinitely adjustable speed • Push-through agitator shafts • Overload protection • Short-term overload operation • Slim casing • Quiet operation • Error code display Technical Data Stirring quantity max. per stirring position (H2O): 100 l Motor rating input: 130 W Motor rating output: 84 W Motor principle: Brushless DC Speed display: 7 segment LED Speed range: 0/6 - 2000 rpm Viscosity max.: 100000 mPas Output max. at stirring shaft: 84 W Permissible ON time: 100 % Torque max. at stirring shaft: 200 Ncm Torque I max.: 200 Ncm Torque II max.: 40 Ncm Speed range I (50 Hz): 6 - 400 rpm Speed range II (50 Hz): 30 - 2000 rpm Speed range I (60 Hz): 6 - 400 rpm Speed range II (60 Hz): 30 - 2000 rpm Speed control: stepless Setting accuracy speed: 1 ±rpm Deviation of speed measurement n > 300rpm: 1 ±% Deviation of speed measurement n < 300rpm: 3 ±rpm Stirring element fastening: chuck Plug-in coupling (Ø): 10 mm Chuck range diameter: 0.5 - 10 mm Hollow shaft, inner diameter: 10.3 mm Hollow shaft (push-through - when stopped): yes Fastening on stand: extension arm Extension arm diameter: 16 mm
