new tds meter or battery change possibly?

[thesoulpatch]

So my inline is dead and was wondering what i should do. Can you even change the battery, or should i just buy a new one and install it? It's from 2016 so it's def lasted a good long while.

yup...see what you mean....cant even find a decent manual for it.....check on the back of the unit....either a screw assembly or a snap assembly....if screw...then easy...if snap...then be careful....
