No Need to Stir, No Membranes to Replace, No Sweat!
Make your job easier with an Orion 3-Star RDO Optical Dissolved Oxygen Meter! 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.
Probes store wet or dry. Sensors easily handle dirty samples, so testing wastewater is a snap. Memory stores the last 10 calibrations. Meter includes batteries.
