Hirst Magnetic Instruments Ltd. offers a calibration service for instruments and equipment manufactured by Hirst and many other manufacturers.
In the case of instruments manufactured by Hirst, they are “calibrated” so that their performance meets its specification (i.e. in 1 Tesla – the Gaussmeter reads 1 Tesla within the stated accuracy).
Instruments from non-Hirst manufacturers, are calibrated by subjecting them to known magnetic field strengths, or flux, and a calibration table is produced showing the instrument’s performance.
Hall Probes should accompany instruments sent to Hirst Magnetic Instruments Ltd. for calibration where applicable.
In the unlikely event of an equipment failure, we also provide a repair service. Ideally the unit is returned to our premises, but on site repair can also be performed. We have a number of demonstration models which can be loaned out during a repair.
We also offer a maintenance facility for our magnetisers, de-magnetisers and characterisation equipment. Our equipment is often used for many years in high volume manufacture. Inevitably mechanical parts will wear or the surface of fixtures may become damaged or badly worn to the extent of exposure of windings creating a dangerous operating condition. We can offer a one off or routine maintenance service.
