Those bl++dy inline TDS meters can be WAY OUT.

I have one on my Ionics system and it reads about 20 to 30 BELOW what the hand held HM digital one does. I double check all the time now and nver rely on the inline one.

i have the handheld one, but i really want one thats inline as to check my ro and di with out water spraying everywhere anyone know the best and accurate ones then?

the display is easy to read and its allways read the same as my hand held before di so im happy with it . i dont no if youve looked on ro-man.co.uk as thats where mines from .
