Pressure calibration
Pressure calibration equipment for a stated range.
Range, medium, accuracy and where the work happens decide the instrument. A portable calibrator, a test gauge and a deadweight or controller are not interchangeable.
What to include
Range, medium, and the certificate you need.
Tell us the pressure range, whether you need gauge, absolute or differential, the medium, the accuracy, and whether this is a field check or a workshop calibration. Process connection, hazardous area and the instrument you are checking against are part of the same description.
If you need a UKAS-accredited certificate, say so. Obsidian Dynamics is not UKAS-accredited. Optional calibration is arranged through a third-party laboratory, and only when that path is actually available for the instrument. The enquiry should not be read as an accreditation of this company.
A discontinued calibrator or test set you must replace like-for-like belongs with Instrument Exchange. A new requirement for a stated duty can start here or on Source.
