For most instruments our standard service offers a 1 week turnaround and doesn't require you to "book-in" your calibration. Simply send your instruments in along with your contact details and a purchase order (preferred).  For more urgent instruments we have an expedited service which has your instrument carefully managed from receipt to dispatch within 1 day (24 hrs) typically.  We ask that you contact us prior if you require the expedited service to ensure we can allocate resources. There is an additional charge for our expedited service. We like to think of the options as 1 week or 1 day, depending on your level of urgency.

Unless explicitly stated, ALL certificates that we issue are ISO/IEC 17025 accredited with the NATA and ILAC-MRA combined mark on the certificate.  As we are a small specialist laboratory, we do not operate a lesser second level workshop or offer non-NATA / "NATA-traceable" certificates.

Obtaining an ISO/IEC 17025 accredited calibration from an NATA accredited laboratory, like APL, means that the calibration of your instrument has been performed by trained and competent technicians, following valid test methods, against standards that have unbroken traceability to the International System of Units (SI). When you receive an accredited certificate from Australian Pressure Laboratory you can be confident that our evaluation of your instrument is true within our stated uncertainties, and that we are continually assessed through audits and proficiency testing to prove this. Obtaining a "traceable" calibration certificate simply means that your instrument has been tested against a calibrated reference but it does not offer any assurance on the competence of the technician or methods used.  This does not mean it is a poor certificate, but it does mean that its quality may be unknown and has not been verified by the relevant external body (NATA or other ISO/IEC 17025 accreditation body).

We are primarily focused on calibration services and we do not represent or stock any particular makes or models of instruments.  However our relationships with manufacturers and instrumentation companies through calibration allows us to buy-in instruments for our customers at competitive prices as needed.  If you would like us to recommend and/or source instruments for you, feel free to contact us.

We are in a fortunate position where we get a chance to test almost all common makes and models of pressure instruments on the market, yet we do not represent any manufacturers. This enables us to offer unbiased opinions and recommendations to our customers without bias.  If you need to purchase new pressure measurement instruments and are unsure what to buy, feel free to contact us for an opinion. We can also refer you to where to purchase them, or buy them in for you if we can get competitive rates.

We seek out the best laboratories nationally and internationally for calibration of our reference equipment to ensure we can offer good traceability with low uncertainty to our customers.  Currently our primary pressure and vacuum references are calibrated by NMI Australia, and our electrical references are calibrated by a Fluke UK and ISO/IEC 17025 accredited laboratories.

Yes, we also have a high accuracy accreditation in a broad range of electrical measurments, with particular focus low uncertainty in electrical ranges that are commonly found in process calibrators (DC voltage and current, RTD and thermocouple scales by electrical simulation).  For other measurement areas, we may be able recommend or subcontract to other accredited laboratories with an appropriate capability, so if your are unsure, please feel free to ask us.

We like our customers to know how we will be testing their instruments, including the number of test points, warm-up time, testing before and after adjustment, etc.  Please see our explaination of test methods here. We encourage all of our customers to read the test methods and we link to them on all of our quotes.  

We have purchased a large range of calibration kits and display devices for common modular calibration systems.  A list of the external / removable module systems that we can calibrate without your display are shown here.  Please feel free to contact us for confirmation before sending your modules.
