BPI DIGITAL 5 STROKE GRADIENT MACHINE #12404

This instrument incorporates the proven 4-stroke gradient process. The built in timer automatically turns it off and removes the lenses from the tint when the cycle is complete, giving the technician time for other tasks. Produces gradient lenses and solid tints under timer control.BPI 5-Stroke Gradient III is made of 100% low maintenance stainless steel. The 5-Stroke Gradient III has a one year warranty. In the 4-Stroke gradient process, the lenses are lowered further into the dye on each stroke. After the fourth stroke the gradient repeats the cycle. This mechanical process creates a smooth gradient effect. The 5-Stroke Gradient can also process a solid tint. The lenses will be removed from the tank at the end of the timed period.
