No Need to Stir, No Membranes to Replace, No Sweat!
Make your job easier—get one of these Optical Dissolved Oxygen Meters! They give 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. Each Meter includes batteries.
Meter Kits add a stainless steel RDO probe guard, optical cap, batteries and manual. Meter Kits with Hard Case add a stainless steel RDO probe guard, optical cap, batteries, manual and hard case.
