As the Subject states, my Sybon refractometer is less than desirable at holding an accurate reading. I calibrate it with Randy's homemade calibration fluid to 35ppt and 2-5 days later is is reading 37ppt. This is constant and with less than 1 yr use, I'm thinking of returning it. If the vendor is non-cooperative and since recalibration is time-consuming, I may just buy a new one. The prismn is rinsed and dried after each use and kept in a cool, dry place when storing. It has NEVER been dropped on a hard surface or immersed. What's the deal...did i get what I payed for?
So, what is the general consensus on 'best' ATC refractometer? I spent the $43 on the Sybon and unless another 'cheap' one has a proven track record I would likely not spend that little again.
What's anyone's expereince?
Thanks
