The Hu-Friedy ultrasonic cleaning monitors are used for monitoring the efficiency of the cleaning process in ultrasonic cleaners. The monitor strips contain a Test soil that Mimics the presence of blood and tissue that may be found on an instrument after use. During the Test the monitor strip is assessing multiple variables of the cleaning process including cavitation, time, temperature, and detergent. Full removal the Test soil from the strip indicates an effective cleaning process. The Test strips should be used in conjunction with the holder (ims-1200h) on a daily or per load basis.
