In-line TDS meter feedback

[kaceyo]

I'm considering discusgeo's In-line TDS meter as an alternative to hand held type. If I get it I'd place it on the hose from ageing barrel to the aquarium as its running 24/7 anyways. The info givin sais it needs no calibration from the factory but can it be calibrated occasionely? Any and all info will be appreciated. Thanx, Kaceyo

Kayceo,
I sell those as an option on RO units, and I have only had 2x complaints about some of them. They were blowing their calibration settings after a short period of time and having to be recalibrated. I used 1488 uS (744 TDS) solution to recalibrate them.

HTH,
