How often should pressure and temperature sensors be calibrated in a steam sterilizer?

Pressure and temperature sensors in a steam sterilizer should be calibrated at least every six months, or more frequently according to the manufacturer's recommendations and the facility's quality control program. These sensors are critical for accurately monitoring and controlling the sterilization process. Regular calibration ensures that the readings are accurate and reliable, guaranteeing that the sterilizer is operating within the validated parameters for effective sterilization. Calibration should be performed using calibrated reference standards traceable to national or international standards. Calibration records must be maintained to document the calibration dates, procedures, and results. If the sterilizer is used frequently or if there are indications of sensor drift or malfunction, more frequent calibration may be necessary.
