The Test-Master testing screens are designed for coarse materials of mid-range density such as limestone or gravel. Similar to the G2705 except the Test-Master has an internal counter balance which eliminates the need for permanent anti-vibration mounting in trailers or near sensitive equipment. Balancing is achieved through the internal rotating weights which equalizes the action of the vibrating mechanism. The G2781 & G2782 holds six screen trays and pan. The G2785 & G2786 holds seven trays and pan, but closer tray spacing limits use of these models to 3/8" tray sizes and finer for the bottom four tray slots. The enclosed outer case confines dust and reduces noise. Also featured is a built-in timer which can be programed up to 99 min., 59 sec. The screen trays are hydraulically clamped in operating position by the foot-pedal clamping device. Five coarse series trays are furnished with the Test-Master: 2", 1-1/2", 1", 3/4", and 1/2" (or other combination of coarse trays).
