Milwaukee salinity ?

[Notsolostfish]

Okay so my tank is 1 month old, and my milwaukee ma877 is calibrated. My tank salinity is 1.025. And my device is only off by 1. So when i get 1.026 on the device I know im at 1.025 also confirmed by ICP. Iv been getting 1.026 stable.

Today i bought new distilled water as i ran out, and calibrated it to 0. And then tested my tank. 1 click shows me 1.025 and then another click is 1.026. It’s fluctuating. Is that my ato dumping too much? Or what’s that means? One click 1.026 and then another click 1.025 im confused by this behavior.

It could very well be within the margin of error for the tester. You realize that’s a difference of .001
That’s actually pretty good. No need to worry about a .001 difference.

It’s with in margin of error. Also you could be at the 1.025 / 1.026 cut off line. It’s normal for it to sometimes bounce .001 do to reading error.
Nothing to worry about

The milwaukee does have a wide error range, and obviously if you are on the dividing line between two of it units of measure, the result is expected to jump back and forth between them.
