Refractometer Question

[TomW]

I was given a refractometer recently and I can't get it adjusted down
to 0 using RO water. It's about 6 years old and probably requires
recalibration and possibly service (although it looks to be in perfect
shape).

Can anyone point me in the direction of a company that can provide
these services?

TIA

Probably cheaper just to buy a new one as they're only about $30...
