The calibration period is one year. We recommend to double check the conductivity once per month with a
conductivity reference solution. If biological material grows inside the cell, it could interfere the accuracy
of the conductivity measurement.

We know that competing companies do not recommend a monthly test of the conductivity measurement,
some even offer this as a "feature" of their meters. From our more than 25 years experience in developing
dialysis meters we strongly recommend monthly testing as a safeguard precaution.
 

As the conductivity electrode is part of the calibration process, it must be included with the meter.
If your meter has a flow probe, it must also be included with your shipment. There is no need to
ship the battery charger or other accessories.
