We understand the pressures faced when you are updating records or tracking down relevant documentation for an upcoming audit. At Hirst we pride ourselves on our customer service and the ability to assist you when you find yourself in a tight spot. 

Our Replacement Calibration Certificate Service  will ensure that you have the information you need, when you need.

Following payment you will receive both a hard and soft copy of your current* certificate, usually you will receive your soft copy within 24** hours of purchase and your hard copy will be delivered within 5 working days.

If you require multiple certificates, please note that as our calibration service is offered on a per probe basis, the replacement calibration certificate will only be valid for the specified probe.

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 laws
  
• Maintain national and international standards
  

All calibrations carried out at Hirst Magnetic Instruments are traceable to National Physical Laboratory (NPL) standards using Nuclear Magnetic Resonance (NMR) technology. Once completed, all calibrations come with a new calibration certificate valid for 12 months. UKAS calibrations are available on request.

*We are only able to replace current certificates, once your gaussmeter has been recalibrated the previous certification is overwritten.

** Subject to availability, we will be in contact should there be any concerns
