I didn't know you had to calibrate TDS meters. can you elaborate more on what TDS meter you have?

i have a hanna primo . tds meter there is a soultion that it has to be calibrated in.
before you use it. all the ones i have seen use the fluid as do some ph meters. i havent ssen any that dont use the fliud. do you have one that doesnt need to be calabrated.

Mine is hooked up inline with my ro unit, and has never been calibrated. I didnt think they needed calibration either.

you can see my unit here:

it did not need calibrated. I thought they work just by testing the conductivity of the water...but I might be wrong.

Maybe there are different types...some that need calibrated. dont' know.

where'd you get the TDS meter? Did they not have the calibration fluid there?
