Refractometer Calibration ....... SO CONFUSING

[crustytheclown]

Ok. So i got the Pinpoint Salinity Monitor 53.0 mS Calibration fluid from American Marine and im trying to calibrate my refractometer. I have a lot of questions.....
1. Does the refractometer need to be at a certain temperature before calibrating? If so what temp and how do you know a refractometers temperature?
2. Does the calibration fluid need to be at a certain temperature?
3. When zeroing out the refractometer w/ DI water, does this water need to be at a certain temperature?

pretty confused

no
no
no

assuming your refracto is ATC

 

[crustytheclown]

what is atc?

 

[amonchak]

auto temp compensating

 

[dv3]

most reef refractos are ATC these days ...i cant say in the few years that i have been in the hobby that i have seen anything other than ATC but i hear they are out there

 

[crustytheclown]

it is

when i purchased mine it said not to calibrate to 0 but to use the calibrating solution instead due to the fact that the DI water may have dissolved solids in it.
