[Wine] Measuring SO2 in our red wine

Hi everyone

We have made four different red wines, the cab sauv. has been in Hungarian oak
for almost year and a half, the Grenache is in steel tank since last October,
syrah is in steel tank since last October and the syrah /grenache blend is in
steel tank since last October.  We bought a Hanna 84100 SO2 titrator to measure
free SO2.  Our inital readings were between 2 and 5 ppm of free SO2 on all our
reds. We added  potassium metabisulfite using More Wine Guide to Red Wine Making
formula.  We retested and the SO2 levels were the same.  Not sure if the Hanna
instrument is malfuncting or all the SO2 is bound up?  We are reluctant to keep
adding the Metabisulfite for fear of over concentrating.  Any help would be
greatly appreaciated.

Thanks

Wrong forum,?
But the SO2 is either probably bound or the sample you took was?oxygenated?in
the taking, but why do you want to sulfur a good wine to death anyway ?
