Recalibrating the TOC Monitor
The TOC monitor is equipped with a UV radiator. This UV radiator is subject
to ageing and must be replaced at regular intervals. To ensure accurate TOC
measurements after replacing the UV radiator, the TOC monitor must be
recalibrated by Sartorius Service.
The normal service interval for recalibration is one year. If your TOC
measurements are more frequent, the UV radiator ages faster. This is the
case when continuous measurements are performed and the Arium
®
Comfort system is in frequent use. In such cases, earlier recalibration may be
required. If measurement is performed at specific time intervals, e.g. once a
day, the recalibration can be adjusted to up to 24 months.
Your Arium
®
Comfort system issues warning message at the intervals 6, 4,
Sartorius Service.
If the service interval for the TOC monitor has expired (at least after a year),
the TOC monitor on your Arium
®
Comfort system will be deactivated. You
cannot measure TOC again until after recalibration. Ultrapure water can
continue to be dispensed.
The Arium
®
Comfort system alerts the recalibration of the TOC monitor at
the intervals 6, 4, 2 weeks. Please inform your service technician after the
first message.
