Overhead stirrers, the OS40-Pro LCD, OS20-Pro LCD, OS40-S LED and OS20-S LED
Overview
The OS40-Pro, OS20-Pro, OS40-S and OS20-S are efficient and carefully controlled digital overhead stirrer models for the safe and effective mixing of large volumes of liquids.
The OS40-Pro LCD and OS20-Pro LCD digital overhead stirrers allow the user to set the required torque and speed, and observe their true values on an easy-to-read LCD display. An accurate microprocessor controls stirring speed and guarantees precision in the speeds achieved.
The OS40-S LED and the OS20-S LED models provide a precise display of the actual speed that is selected via an analog dial.
Both LED and LCD models have over-torque protection to automatically stop motor in case of continuous overload. Anti-spill microprocessor control insures the slow start up of speed to prevent sample spills.
