DICKEY-john GAC 2500 Service and Calibration

During the service the instrument is thoroughly cleaned and electronically standardised, instrument operating system software is upgraded to the latest version and the national calibration values for UK crops are updated as necessary.

Following standardisation a detailed test report is supplied showing the instrument permittivity characteristics in comparison to the UK reference standard instrument, the IR temperature performance is checked against a UKAS temperature probe, and the internal balance is verified using specialised weights.

The Hectolitre weight calibration is tested in accordance with BS EN ISO 7971-3, samples for this calibration are derived from our National standard 20 Litre chrondometer, a detailed test report and certificate of calibration is supplied, with appropriate instrument labelling.

Any important calibration updates are emailed directly to you; additional or improved calibrations are installed at point of service. Any requirements for new calibration values prior to service can be arranged as soon as your booking is received.

The following support is included in the cost of service;

  • breakdown coverage (including loan equipment)
  • subsidised repair rates (out of warranty)
