Sound and Vibration Instrument Hire and Calibration
Acoustic Calibrator Hire
All our meters are delivered with calibration certificates. However it is good practice to calibrator equipment before and after measurements to check the system including any cables etc.
It is also standard practice to include the type and serial number of the calibrator used in any reports.
