Replacement SO2 probe for the SC-100, SC-100A & SC-300 SO2 Analyzers. Simply rinse with deionized (distilled) water when done with measuring SO2 and let it air dry. The SO2 electrode does not need to be stored in any solution and should last for a long time but be careful not to bend the wires at the end of the electrode.
I have an older version of the Vinmetrica pH, TA and SO2 tester. The original model only has a single Male BNC connector on the top of the analyzer. The pH/TA probe AND SO2 probe BOTH have Female BNC connectors. This replacement SO 2 probe will not work with the older model.
