What we do

While we always encourage our customers to send their instruments to the lab for calibration in order to take advantage of lower uncertainties and less technician and travel costs - we do appreciate some calibrations have to be done on site.

Why use an IANZ accredited provider?

We must take all practicable steps to ensure the safety of people, property and plant. In order to do this best we need to be assured our equipment is measuring and monitoring as it should.

An IANZ endorsed certificate ensures the people who test your equipment have had the appropriate training and know what they are doing. Also the reference equipment used to test your instruments is certified and is right for the job. It also means the people doing the calibration have been independently audited by technical experts to ensure correct techniques are being used. IANZ calibrations give you the confidence in your calibrations. Read more
