Long term accurate monitoring of dissolved oxygen levels even in still water

The D-Opto range of dissolved oxygen instruments monitor dissolved oxygen levels in streams, rivers, lakes and marine environments with minimal on-site maintenance and servicing.

Unlike conventional polarographic dissolved oxygen sensors, the D-Opto sensing element utilises fluorescence to measure dissolved oxygen – it doesn’t consume oxygen – so the measurement of dissolved oxygen by the D-Opto is unaffected by water flow.

Rugged low power consumption and low drift ideal for the remotest locations

Self contained
Simple to operate and easy to deploy
Minimum on-site maintenance and servicing
Logs data once per minute
Doesn’t require vigorous flow past the sensor to get a stable reading
Long term, time course data logged allows for more accurate assessment of oxygen dynamics
Quick and simple field servicing only after extended periods
Technology prevents bi-fouling and deposits

With more than 20-years experience in the environmental and industrial science and sales field, ENVCO Global offers unmatched customer service, technical expertise and scientific experience.

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.
