Knight’s unique probe life enhancement circuitry, first introduced in 1994, samples the wash tank solution in short bursts of 1/100 th of a second long. This rapid, short sampling greatly enhances probe life while holding the tightest concentration levels possible. The Dual Range Concentration setting provides broad, linear adjustment ranges for easy setup in all types of water conditions. Knight’s PWM (Pulse Width Modulation) variable speed circuitry ensures linear rinse motor speed adjustment and maximum brush life.
