refractometer searching

[kevvin27]

Does anyone know if this is a good one to get? New Salinity Refractometer 0-10% ATC Aquarium Salt on eBay.ca (item 190382083810 end time 24-Mar-10 23:07:59 EDT)

It looks fine -- it has the two scales, salinity and SG, so that's good. I know someone ordered a refractometer off of Ebay (I don't know if it was the same one) and it only came with one of the scales, so hopefully this one has both -- if not, no big deal, you just have to memorize which number corresponds to SG ;)

Don't forget to order some calibration fluid too -- you can get that on Ebay for around $3 or $4 (search for refractometer calibration fluid at 1.026)

Calibration fluid???? Whaaaa???? My destructions say use RO water....

 

[Bifferwine]

The RO water will calibrate it to 0. But it may not be as accurate when you measure your tank's water, at 1.026.

So....who calibrates the calibration fluid? Do you by chance sell this stuff???? LOLLOLOLOLLLL

 

[Bifferwine]

It comes from a scientific instrument lab. Why so many questions?!?! :cry:
