Refratometer - My 2 cents worth

[Fragzilla]

I have been using one of those plastic rectangle testors for years and relying on it.

The other day I broke down and bought a proper refractometer.

To my amazment my old testor was reading very low LOTS

When I tested it with my old my reading was 1.0025

New meter 1.0030

I suggest to anyone useing one of the cheep testors go out and get a good one.
