Pressure Calibration Workshop

Training course

This workshop is a practical one-day session dealing with all aspects of pressure gauge and transducer calibration. It is especially useful for staff involved in testing and calibration of pressure gauges by comparison against reference pressure gauges or deadweight testers.

Calibration is more than simply checking or adjusting an instrument. Calibration involves ensuring the gauge under test is working properly, ensuring the reference instrument has a traceable calibration, comparing the two instruments using an appropriate method, and calculating the measurement uncertainty.

This workshop teaches attendees an efficient method to calibrate pressure gauges that meets the technical, quality and legal aspects of calibration. A feature of the method is the straightforward way that the measurement uncertainty is calculated.

The presentation includes many demonstrations and hands-on activities that will be of interest to new and experienced users. By the end of the day, attendees should be able to calibrate a pressure gauge, calculate the associated measurement uncertainty, and carry out regular in-service checks on reference equipment.


The standard fee is $1,020 for each of the first two attendees from an organisation and $714 for each additional attendee.

Peter McDowall

Research Scientist | Mass and Pressure

Prior to joining MSL in 2019, Peter spent 5 years researching air and moisture flow within homes and buildings for the Building Research Association of New Zealand. As part of this research he conducted experiments examining indoor air quality, ventilation and the efficacy of photo-catalytic oxidation as a process for reducing mould growth in New Zealand homes.

He received his PhD in atomic physics in 2014 from the University of Otago where he built an atom interferometer based on laser cooled atoms subjected to periodic pulses of near-resonant standing waves of light. The output of this interferometer was a determination of the fine structure constant α via the ratio of h/m obtained from direct measurement of the Talbot time.
