im looking at the hanna HI 98129 and HI 98130 meter, there the ph/tds/ec meter combos but one is low range ec and the other is high range ec. which one do i need for hydro? im guessing the low ec but i would like to be 100% sure before i buy. thanks everyone
You dont wont to go above 1.6 EC so the low range EC bro just chk out the range before you purchuse. Hope this helps
Both would work - but I would go with the lower range.... it's usually just a decimal place moving around Low range might be 1.6 High range might read the same thing as .16 or .016 As you can see, it's kinda mute.
