at the design referance temp (60 degrees F)
34.5ppt is actualy 1.026 not 1.024.
1.024 would be 31.9.
but this is confused more because people don't list the referance temp they are using for therte tables so you don't know. then I found two tables that said 80 degrees but were the values for 70 degrees
the problem is that you are not measuring salinity you are measuring the SG then coralaiting it to lines some one wrote beside the SG ones which will only corasponde at 60 degrees.

well you could buy and ATC one for 10 or 15 bucks more
but you will have to use the SG scale as the salinity scale will be wrong.
