This portable batch mixer has enough power to mix up to 52 gallons (200 L)! It offers one of the highest torque settings on the market—4248 in-oz (30000 N-cm). The enclosed fan-cooled brushless DC motor maintains a constant power transfer to the shaft at speeds up to 1500 rpm. Adjustable chucks accommodate up to 5/8" (15.8 mm) diameter impeller shaft. Ideal for laboratory and industrial uses, the mixer features RS-232 and USB interfaces to record date, time, speed, and torque data. Easy-to-use resistive digital touch-screen control enables you to select time and speed with a gloved hand or pencil tip. Other functions include alarms, timers, torque zero, torque min/max setting, and clockwise and counterclock rotation. Safety features include a shaft/check guard, chemical-resistant housing, and overload, overheat and vibration protection. A safety screen protects the display from splashes. Mounting bolts make installing on existing equipment easy.
