Overhead laboratory stirrer EUROSTAR 20

digital

Laboratory stirrer designed for simple to strong stirring tasks for quantities up to 15|25|40|100 liters (H2O). Automatically adjusts the speed through microprocessor controlled technology within the speed range of 0/30 - 2000 rpm. 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 Motor rating input: 70|118|176 W Motor rating output: 42|84|126 W Motor principle: Brushless DC Speed display: LED Viscosity max.: 10000|30000|50000 mPas Output max. at stirring shaft: 42|84|126 W Permissible ON time: 100 % Torque max. at stirring shaft: 20|40|60 Ncm 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 Chuck range diameter: 0.5 - 10 mm Hollow shaft, inner diameter: 11 mm Hollow shaft (push-through - when stopped): yes Extension arm diameter: 16 mm Extension arm length: 220 mm Nominal torque: 0.2|0.4|0.6|1 Nm Housing material: alu-cast coating / thermoplastic polymer Dimensions (W x H x D): 86 x 248 x 208 mm Weight: 3.9 kg Permissible ambient temperature: 5 - 40 °C Permissible relative humidity: 80 %
