The redesigned Test-Master® testing screen now features an easily controlled, integrated hopper for easier introduction of sample material and vertically-hinged front panel doors for improved access and clearance. 1.6英尺³(45.3L) hopper is hinged at the rear and allows the sample to be introduced incrementally as the machine is running. When the hopper is closed, a panel blocks dust from escaping through the opening. The narrower panel doors require less space to open and fold flat across the front of the unit. The doors also feature a safety interlock switch that disables the Test-Master® when open.
Test-Master screen shakers are available in a six and a seven-screen tray capacity models. Both units feature the same reliable counterbalanced drive assembly, fully enclosed operation and electronic digital controller as our previous models. Sample vibration characteristics are identical to Testing Screen 瓶 and the screen trays are interchangeable. Internal rotating counterweights of the Test-Master® drive system equalize the vertical screening action to assure smooth, quiet operation and prevent transfer of vibrations to other lab instruments.
Gilson Test-Master® screens are sold without screen trays or dust pans, which need to be purchased separately for operation. 订购时指定尺寸. 在这两个模型中, the dust pan may optionally be placed on the bottom shelf of the unit, freeing up an additional slot for a screen tray.
