We continue to be puzzled as how they can do that.i.e., be on for RO/DI and at the same be on for seawter at 35 ppt, when it is not a seawater refract. When you put the drop on the refract it should have read 36.5 and turning then screw to read 35 it should be below the zero with RO/DI. That is what you will get with any std lab refract. I guess the cheapness of these refract and the material some how off-set things from normal but that is good I guess for some that luck out. It would be interesting to see what it would read if some one tried a 35 gram solution on it vs a 36.5
