6 Calibration
Please keep in mind that part I of DIN 16 005 requires reference instruments to be at
least four times as precise as the device being calibrated.
Equipment used to test halstrup-walcher pressure calibration devices are monitored
continuously and our instruments are themselves calibrated using reference
pressures based on national standards.
In order to maintain this high level of quality over a long period of time, we
recommend sending your pressure calibration device to the manufacturer for
recalibration at least once a year. A halstrup-walcher certificate of linearity or a
calibration certificate from a testing facility accredited by Germany's National
Accreditation Body (DAkkS) is available upon request.
Please note when the next calibration is due (indicated on the rear of the
instrument).
