Since 1996, our parent company, DICKSON, has provided precision equipment for technician teams to service process control systems around the globe. For a decade we relied on other commercial labs to keep our equipment in good repair but the need for reliability demanded a better solution.

The labs we’d tried, while competent on the bench, had little knowledge of circumstances in the field. Long delays and poor communication were the norm. So in 2015, we built the exception.
