Calibration period
When delivered new from the factory, each device is adjusted and calibrated before shipment. To ensure
reliability, we recommend the following intervals for verifying calibration:
Parameter
Calibration period
Temperature
Once per year
Conductivity

Pressure

Flow

pH
Before each use
A complete function test and calibration of the device should be done once a year.
According to ISO 10012-1 “General Quality Assurance Requirements for Measuring Equipment" the error
attributable to calibration should be as small as possible. In most areas of measurement, it should be not
more than one third and preferably one tenth of the permissible error of the confirmed equipment when in
use. In other words the accuracy of the references to adjust or calibrate the HDM must have at least a tree
times higher accuracy.
For liability reasons you should not carry out these tests and calibration and verification yourself. If IBP
performs the calibration, you will receive a calibration certificate in accordance to ISO9001 which
documents the calibration/verification results.
