Wherever measuring instruments and probes are used in quality-related areas, calibration of this equipment is required. This is because even the smallest measurement errors can have critical consequences.
In most cases, ISO calibrations which fulfil the requirements of the various standards and are traceable to national standards are sufficient. What are referred to as ISO certificates are then issued for these calibrations.
This ISO calibration certificate for volume flow (suction or blowing) means your volume flow hood is calibrated at the following points:
300, 600, 900, 1200, 1500 Nm³/h.
If you want ISO calibration at other calibration points, you can also order an ISO calibration certificate with freely selectable measuring points (0520 0154).
