Refractometer; New ref.std.

Boomer · 10-21-2006, 02:14 PM

There has been some correspondence going with Lou Dell of American Marine, Randy and a reefer. Lou has told us that his ref. std. of 53 mS for conductivity/Salinity will work with refractometers. I'm looking to see if it will or maybe work for Hydrometers as well.

Boomer
just got the 53.omS calibration fluid.
im gonna wait a couple hours so the fluid goes to room temp.

do you have any other tips.
i have the milwauki brand refract.

thanks

vic

Boomer · 11-16-2006, 05:37 PM

Yah, good Idea I'm sure it is really cold

No other tips for now, other than it does not make any difference who's refract it is. No matter what it says, with the 53mS on it , re-cal to read 35 ppt, 3.5 % or 1.0265 SG. Once it is warmed up enough put a drop on it and let it sit for 1 min then take the reading.

Final note; This will only be good for reef tanks or FOT. It will be off for lower salinity as the scale on the refract is not a seawater scale but a table salt scale. Pretend the scaling is like.... in. vs cm. And 1 cm does not = 1 in. This means that the higher you go above 35 ppt or the lower you go below 35 ppt the more off it will be. There will be an article out on this soon. I'm looking at it right now

It will show these off-sets graphically. We are good, close enough, from about 33 ppt to 38 ppt or 1.024 to 1.028.

swissgaurd · 11-16-2006, 06:16 PM

thanks boomer i was going to calibrate it to 53ppt

vic

Boomer · 11-16-2006, 07:15 PM

NOOOOOOOOOO !!!!!!!!!!!!

That 53 is not ppm but mS. 53 mS = 35 ppm

swissgaurd · 11-16-2006, 10:05 PM

well Boomer no calibration needed.does this mean i have a proper salinity chart

35 ppt bang on

so i gather i will be able to read lower salinity meters

how often do you figure you should check to see if its in the proper range.

thanks so much

vic

Boomer · 11-17-2006, 01:17 AM

Vic put some RO/DI water on it and see if it reads zero or below zero

swissgaurd · 11-17-2006, 08:56 AM

boomer ro and distilled both read zero

Woodstock · 11-17-2006, 09:18 AM

I just ordered the salinity calibration fluid also.

Swissgaurd, could you take a pic of your refractometer for us?

swissgaurd · 11-17-2006, 09:49 AM

i borrowed the pic from custom aquatics
its a milwaukee

vic

swissgaurd · 11-17-2006, 09:52 AM

i can still take some photos of it maybe i can get the scale my camera is in the truck at the moment.and its raining

Woodstock · 11-17-2006, 09:54 AM

That pic works great. Thanks! I tend to remember photos better than just a name.

It is nice to know which refractometers are calibrated from the factory for our tanks. I have the blue one that Boomer suggested a while back which is supposed to be correctly calibrated. I ordered the calibration solution to double check it.

swissgaurd · 11-17-2006, 09:58 AM

i saw a refract for sale that came with calibration fluid i think it was a sybon
kinda nice or are they trying to tell you somefin

Boomer · 11-17-2006, 01:13 PM

swissguard

We continue to be puzzled as how they can do that.i.e., be on for RO/DI and at the same be on for seawter at 35 ppt, when it is not a seawater refract. When you put the drop on the refract it should have read 36.5 and turning then screw to read 35 it should be below the zero with RO/DI. That is what you will get with any std lab refract. I guess the cheapness of these refract and the material some how off-set things from normal but that is good I guess for some that luck out. It would be interesting to see what it would read if some one tried a 35 gram solution on it vs a 36.5
