Recently we have been worried about reefers using and assuming that the refracts
that ever
one has been using in this hobby should be off - 1.5 ppt or -.15 % or - .0015
SG. We have
been telling people in short to raise the seamix "15 units" higher to = 35 ppt
( to read
36.5), 3.5 ( to read 3.65 and 1.0265 A( to read 1,0280).
These tests have been completed on a number BUT the SAME brand refracts. These
are the
ones on the below image. Low and behold, they should read these values on a good
lab
refract and would need these adjustments but about 95 % of the ones reefers are
using are
off from the factory that exact amount we are correcting for :lol:
So it appears that with the these Chinese refracts, zeroed to RO/DI water, that
they are
right on when tested to a seawater std, when they should not be. So it reads 35
ppt, 3.5 %
or 1,0265 no adjustment is needed to our surprise. Just use as is :D
Note: This is only for these refracts !!

I made an error on this post. The ones tested are the blue ones that most people
have,
made by Xiamen Ming Xin Instrument Company. Both
Xiamen Ming Xin Instrument Company and Huake Instrument Co., Ltd ( the black
ones) use
the same model number RHS-10ATC.
