Infrared Radiation Thermometry Workshop

Training course

This is a practical course covering problems with the use and calibration of infrared radiation thermometers, including reflections, absorption, emissivity, and instrumental effects. The course builds confidence in non-contact temperature measurements in the range −50 °C to 2000 °C.

RT hero


Infrared radiation thermometry is a fast-growing area of temperature measurement. Applications range from high-temperature measurements in the hostile environments typically found in the petrochemical and steel industries, to low-temperature measurements in food processing and storage industries where non-contact measurement is important.

More than for any other type of thermometry, reliable measurements are dependent on the expertise of the user, and can only be obtained through a thorough understanding of the principles and best measurement practices. The aim of this course is to provide that knowledge and understanding.

The course is interactive to ensure you benefit from the experience of the presenter and fellow participants.


The early bird fee is $965 for each of the first two attendees from an organisation and $675 for each additional attendee.

The standard fee applies from 1 June 2023.

Peter Saunders

Distinguished Scientist | Temperature and Humidity

Peter has been working at MSL since 1993 in the area of radiation thermometry, carrying out research in both metrological radiation thermometry and industrial applications. He has worked as a visiting researcher for eight months at IMGC (now INRiM) in Italy, where he investigated the application of CCD cameras to radiation thermometry.
Peter has published more than 70 papers and articles on radiation-thermometry-related topics, and is author of the book Radiation Thermometry: Fundamentals and Applications in the Petrochemical Industry. He won the NZ Royal Society Cooper Medal in 2004 for research he carried out in understanding the physical basis of equations used in the calibration of radiation thermometers. He represents New Zealand on the CIPM’s Consultative Committee for Thermometry (CCT) is an active member of the CCT Working Group on Non-Contact Thermometry.
Scientific highlights for Peter include work on: the size-of-source effect in radiation thermometers, the measurement of non-linearity using a combinatorial technique, analysis of a double-wavelength technique for measuring thermodynamic temperature, calibration equations for radiation thermometers and uncertainty propagation, and reflection errors in industrial radiation thermometry.
Peter is a technical expert for many IANZ accredited thermometry laboratories in New Zealand.
