The laboratory stirrer model DLS is characterized by a high torque allowing their use with medium viscosity liquids. The powerful motor with a sturdy construction is microprocessor controlled assuring a constant speed also if variations of viscosity of the stirred liquid occur. Choice of stirring speed between 50 and 2000 rpm. A progressive start avoids spillages of stirred liquids. A safety system against «over-loads» protects the equipment if an uncorrect operation or blocking of motor occur. The quality of manufacturing materials allows a continuous noiseless and precise operation, absolutely reproducible. The used building technology assures a safe and easy use with a limited volume and weight. The accurate ergonomic project, the modern and compact structure make the stirrers appreciable not only for their technical features but also for the nice design. The model DLS is equipped with two digital displays showing clearly the set and the actual speeds.
