Make your job easier with an Orion 3-Star RDO Optical Dissolved Oxygen Meter Kit! Measure dissolved oxygen with a 3m cable and RDO probe. It gives you accurate readings at depths with no stirring. You won’t get bad readings from other gases. And there are no membranes to replace. The only maintenance required is a simple sensor change once a year.
