Some times it helps to use the search function here as there is all kinds of good information in the archives.

Who uses distilled water per their owners manual 4 refractometer calibration?

Great investment! --- not having is running some substantial risks.

I must have tried every swing arm type on the market and never felt really satisfied I was getting exact readings before getting refractometer like yours...

Can calibrate using distilled water...or just take down to LFS or local aquarium (what I do) and have them test out for you.

Good luck.

lol thanxs otty, i know i know , but sometimes you get a new toy and want to just tell people you got it,because your excited. or i think i start threads sometimes when i know the answer just because no one around me understands me when i talk saltwater. so i have to get my daily fill of salty talk with people who understand. but i was really confused this time.

thanks omard maybe i will do that im sure they have calibrated lots of them so should be simple for them.
