Will a Brix/SG refractometer measure invert sugar?

Hi all. Apologies if this has been answered elsewhere, but if it was, I couldn’t find it.

During hydrolysis of sucrose, the angle of polarized light shone through a sample rotates (or “inverts”) from what it had been when the sample was still sucrose. Not sure what implications this has for an instrument that measures refractive index.

I see that Milwaukee, Hanna, and other manufacturers make designated meters specifically for measuring invert sugar content, which leads me to believe there’s something different here from measuring refraction through a disaccharide.

Reason I’m asking this is that I brewed a strong bitter yesterday and used a pound of #3 invert syrup. I used a refractometer to take my OG measurement and found that it was about five points lower than anticipated given my boil gravity and boil-off volume. However, when I backed the invert syrup out of my predicted OG calculation, the refractometer reading was spot on.

I know, I should have taken a hydrometer reading. Next time.

For the folks here who have used invert syrup, have you noticed any discrepancy in your refractometer and hydrometer readings?

I use a Hanna digital refractometer,  and often have brewed with invert syrup without noticing any discrepancy.  In fact readings taken before and after adding the Invert to the wort show exactly the increase in density expected.

Should read the same as regular sugar.

Thanks guys.
