Brookfield’s automatic gap setting feature for the RST-CPS touch cone/plate rheometer can automatically set the critical gap between the nose of the spindle cone and the plate of the instrument. The company’s automatic spindle recognition system utilizes a barcode on the spindle shaft to identify the spindle’s cone diameter, angle and truncation value. The RST-CPS Touch reads the barcode and then automatically sets the gap to the proper truncation value for consistent, repeatable measurements. The RST-CPS Touch rheometer operates in both controlled stress and controlled rate modes.
