Hi i know it reads ppm what does it actually tell me.
A customer said what does 000 mean then.i said it means pure water but what is the correct technical term ?

[Ian Lancaster]

Less than 1 part per million total dissolved solids

[Cliff perkins]

What solids ?
Whats all the technical bla bla

[Ian Lancaster]

You asked for the correct technical term.......

.......to put it in the vernacular and as my old Yorkshire granny would have said:

Watter bart ort in

 

[Cliff perkins]

Yes great effort
But if a custy sais what solids i wanna be able to tell them.
I know how it all works but not the technical bla bla,so thought some1 here might.
I forgot the total disolved solids bit 

[Window Cleaning Services]

PPM= particles per million
Particles= minerals and other impurities eg certain metals. Most notable mineral for the customer
                 being calcium..the white stuff left on their car or house windows after spraying with a hosepipe
                 using plain tap water and letting it dry. Particularly in hard water areas. 
generally when the reading gets to 015 on the TDS meter its worthwhile changing the resin.

I will tell you what I say tomorrow Cliff. Well, I'll type it. "You know when you splash tap water onto the windows you get white marks when it dries? Well, that's the minerals in the water. The water I use to clean the windows has all the minerals removed, so when it dries, they dry perfectly clear."

(See what I did there?)

Thanks for advice, I usually change my resin when it get to 05 so even up to 015 still good?

Ive told them exact same thing in past.
Regarding tds i never let mine go above 2 generally for my own peace of mind.
Minerals ,calcium,metals.      What metals ?  Copper any others ?
Any1 think of any other stuff
