  • The disinfection process is a key component prior to sterilizing medical surgical instruments.
  • If disinfection is not completed successfully, sterilization may be severely impaired.
  • Disinfection is sufficient for some products such as bedpans or catheters.
  • Rinsing/cleaning:
    The cleaning and disinfecting equipment increases the temperature to 90 °C, for example, inside the chamber by adding water (usually via spraying systems). 
  • Disinfection:
    The defined temperature is maintained for a period of approximately 60 seconds in order to kill surface germs.
  • Drying:
    The products remain in the chamber for a short period of time in order to evaporate most of the residual water.
  • Placement of the data logger measuring tips on the surfaces of the products 
  • Measurement must be reproducible.
  • The user must be able to prove whether the degree of disinfection (A0 value) has been reached or not.
  • DIN EN ISO 15883
  • testo 190 CFR data logger system consisting of robust data loggers, easy to use software, and multifunction case
  • Measuring range of the waterproof data loggers up to 140 °C
  • Optimal placement of the logger with the aid of the accessory attachement retaining clamps
  • Data loggers with small batteries – can be placed in the ideal locations
