Control dynamics has launched a liquid stirrer, which uses cmos technology for accurate speed control, assuring trouble free continuous operation. The free spinning-rotating magnet spins a teflon stirring bar to stir liquids in open and closed vessels. The solid state feedback control system maintains excellent speed stability despite voltage fluctuations. The liquid stirrer operates at full high torque at all times through the entire range of 100 to 1400 rpm and its special circuitry prevents sudden change of speeds to keep the stirring bar from spinning out. A unique reverse control provides the automatic change of direction of stirring using 30 sec to 3 min cycles. In the reversal mode, there is a catch back feature.If the stirbar flies out, it is automatically caught back during the next cycle, ensuring a fail-safe unattended stirring operation. The timer control is settable from 5 min to 2 hr for automatic stoppage of stirring. The timer can be reset and restarted by a front panel switch. The low profile design uses superior stainless steel top with no seams above the base and also an anti skid rubber base which minimizes handling hazards and avoids awkward heights for adding materials to the stirred liquid.
