Complementing ENVCO Global's centralised purchasing and support services is a foundation of experience and skills to find or develop the best solutions for clients, even when all avenues appear to be exhausted. 

For example, when the market needed to measure oxygen levels in still water and no solution could be found, ENVCO Global drove the innovation of the low cost D-Opto Sensor, an optical dissolved oxygen logger.

ENVCO Global was established in 2004 by Richard Morrow and Murphy O'Neal after the pair recognised an opportunity for expert advice and competitive prices in a market that was dominated by local agents – agents who lacked information and the scientific knowledge required to help customers make good decisions.

'Before ENVCO Global, local suppliers were driven by sales quotas and had very little to no expertise in the application of how a piece of equipment was supposed to be used – half the salespeople didn't really know what they were selling,' says Richard.
