About Group3

      Group3 Technology Limited is based in the city of Auckland in New Zealand.  It designs and manufacture robust scientific instruments for measuring magnetic fields and specialist control systems for a broad range of temperature and magnetic field conditions. 

       It was founded in 1983 and exports 99% of production to over 120 organisations in 24 countries.  Group3 produces the worlds’ most accurate and cost effective Hall Effect Digital Teslameter. It has also developed an accurate analog output magnetic field transducer.

       Since 1991 Group3 has supplied control modules to US manufacturers of Ion Beam Implantation equipment, which are used in the manufacture of semiconductor circuits.

       From this work, and a wide knowledge of particle accelerators in general, Group3 launched a control system, with specific advantages for controlling high voltage equipment: fiber optic communications, high speed and high accuracy. The control system is being used in many universities and research institutes around the world, and on the latest prototypes from a number of manufacturers of medical and industrial particle accelerators.

       Group3 also introduced an advanced controller and I/O module that communicates using the industry standard DeviceNet protocol.

       With over 30 years of experience, Group3 hold the industry benchmark in precision and accuracy.  Having developed proprietary technologies, Group3 is committed to continuous product innovation and solutions aligned with emerging technologies in Science, Engineering, Manufacturing, Technology and Research.

       In today’s instant communication and rapid transport, Group3’s geographic distance is easily overcome through an extensive dealer and distributor network with direct access to the Group3 development, support and manufacturing team for repair and calibration services.
