Holy smokes! That’s a thing? What kind of a jerk would mess with calibration fluid? Some people…
I figured there might be differences in calibration fluids, and I wondered if they drifted between bottles/instruments/time. But I guess I always figured it would be close enough. 34-36 anything would work as long as it’s consistent. I guess I should pay just a little bit more attention to my salinity then I have been. Thanks for the help to all of us
I’m not calibrating my probe by simply testing my weighed measurements, I use the Hanna Solution. I referenced this bc ppl think you need to calibrate every time you test your water. I guess you can, but thats not necessary, and if you feel like you have to do this every time to be accurate, then my belief is those ppl should change their testing method to something they can trust to be accurate without calibrating on every use. My “Method” is my redundancy to see if my sanity probe needs to be calibrated i.e.: if I get a result of 32ppt when mixing, its going to raise an eyebrow. I’d then check my calibration and retest the same water; if I get the same 32ppt reading, then I would determine that my weighing method isn’t 100% (which it has been 98% so far), and the cause would be the salt mix variation, which is not 100% each mix. Now would I change the scale on the next batch… nope, bc it was simply the mixture of the elements used when dissolved, not the practice itself. I bother with the meter bc I use it to check temp…I would still check even without the temp option on the probe, bc it would be dang lazy of me not to use the HANNA meter due to its simplicity.Sorry, I'm not following. If you are just adding salt and water to weight each time, why bother with the conductivity meter that is just "calibrated" to some unknown salinity that matches the 2.5 cups per gallon?
You do know that 35 ppt seawater cannot be made from 35 grams of salt mix plus 965 grams of RO/DI, right?

Lol, yes, I am aware that 35 grams doesn’t equal 35ppt- that weight would almost be untraceable.
