Why book a Hirst Gaussmeter calibration?

Gaussmeter calibration is essential to keeping our sensitive measuring equipment accurate. We do so by comparing the instrument to a standard or higher accuracy. We then detect and correct any deviance from the true reading.

For Hirst Gaussmeters, we advise a recalibration every 12 months as best practice, for valid traceability. Whilst other companies can offer calibration for Hirst equipment, only Hirst can correct deviations from true readings.

It is important to ensure your Gaussmeter is giving true readings in order to:

• Maintain quality control
• Comply with industry specific regulations and
