The recent technical development of health care instruments has brought new challenges to the cleaning assurance. There is not always certainty of suitability of the cleaning methods/ programs/ detergents for all type of instruments. Cleaning process control is therefore very important because in the later phases of CSSD process the cleaning result affects to the success of disinfection and sterilization. Cleaning control is important particularly in the automatic washing machines. The process parameters of them are well controlled indeed, but the final cleaning result highly depends on the non-controlled factors. Washing efficacy is influenced by the detergent, water temperature, time and penetration of the wash shower (or ultrasonic). Good cleaning result is achieved by the right combination of these variables.

EVIT TTDF is a new type of washing indicator by which the cleaning result of the automatic washing/disinfection machines can be controlled. EVIT TTDF- controls the efficacy of the water shower, washing temperature and detergent quality and dosage (TTDF = Time, Temperature, Detergent and Flow).
