The dissolved oxygen electrodes are suitable for different meters.
The DO-958-Q, DO-957-Q, DO-958-L are polarographic electrode.
Cooperated with 400F, 500T, 510T, 310F series meters, the DO-958-Q probe has extended the dissolved oxygen range to 50 mg/L.
The DO-968-HC is optical electrode. It cooperated with DO511T DOmeters.
