Instrotec Ltd was founded in the year 2000 by Donal and Donna Johnston.

This move came after Donal, a time served Electrician with extensive Instrumentation and Control experience, had identified an opportunity in the market for a specialist contractor in the field of Electrical Instrumentation and Instrument Pipefitting. By coupling this specialist expertise with the provision of traditional Industrial Electrical Systems, Instrotec quickly established a reputation in the growing Pharmaceutical and Micro Processor manufacturing sectors as the foremost contractor in the provision of Instrumentation and Control’s systems.

In recent years Instrotec has expanded on its existing Electrical portfolio to establish a proven track record in the installation of various LV and MV electrical systems across a broad range of sectors and to the highest of industry standards. Through strengthening this branch of the company, Instrotec has become uniquely positioned to provide an all-encompassing service across Instrumentation and Control, Building Management and Industrial Electrical systems.

Over the past 20+ Years, Instrotec has become a leading provider of Instrumentation and Electrical services within the commercial and industrial sectors, both in Ireland and Europe alike.
