What TDS Meter Would You Recommend For Checking PPM of 30 Gallon Reservoir?

[MajorGrindage]

I dont need anything fancy like a bluelabs, but if you guys think something like a bluelabs guardian is the best then id consider buying one.

Even just a simple TDS pen would be fine with me, i just want to make sure i get a brand/model that has been proven to give accurate reading.

I have heard Apera makes good pens, but there are so many model numbers im not sure which one to get.

Thanks in advance for any help, it is much appreciated!

I would get two cheap TDS meters and some TDS celebration fluid to keep them both checked. You can find them for under $30 each. You don't need to spend a lot of money.
