OK equipment guru's. This is a comparison of two digital salinity testers.
#1 is the Hanna H198319
#2 is the Milwaukee MA887
So here is my issue, they both read consistently.
How do I know what unit is reading more accurate to the actual Salinity.
What can I do to prove what unit is the more accurate.
I know there will be debate on well this one is trustworthy and that one is not, but I am hoping the responses won't go down that path.
I want to know with the equipment I have, how can I determine what is closer to the actual salinity.
Just for clarification.
Both units prior to today's testing and comparison were calibrated with their respective fluids.
Both calibrated correctly. All of my water temperatures are within 1 degree or less.
I have four tanks a 12G Nano, 110G tank, 230G tank and sump, and a 150G Norwesco mixing tank.
The following results also reflect a higher salinity due to evaporation and the need to add RO/DI water.
Checking today because I have been away for a couple of days and currently I am the auto top off unit.
The Nano came out to a .003 difference the rest were consistent at .002. I expected this as its a Nano.
12G Nano tank Temp 78.5
Hanna 1.028
Milwaukee 1.031
110G Tank Temp 79
Hanna 1.027
Milwaukee 1.029
230G Tank Temp 78.5
Hanna 1.027
Milwaukee 1.029
Storage tank Temp 77.5 (This tank is in the shop and harder to keep warm.)
Hanna 1.026
Milwaukee 1.028
As everything is alive and seems to be healthy in the Nano at a Milwaukee reading of 1.031 I wonder of its accuracy, over the Hanna.
How high does Salinity have to be to see things going south?
So how or what can I do to know the unit that is closer to reality?
