A description is given of the device developed for use with a 10-gallon vertical mixer of figure-of-eight design fitted with two equispeed semi- helical solid blades rotating in fixed bearings. Blade-to-wall clearances are approximately 5 mm. High spots are detected from a linear reproduction of clearances on a paper record. The device can readily be used for a wide range of blade sizes and clearances. Risk of detachment from the blade is slight and resultant damage unlikely due to lightness.
