TDS Meter

[zebrafish]

Ok I just got my TDS meter; I was hoping to get instructions on what suitable ranges are. But is just gave me operational instructions. I did buy calibration fluid and have completed that. What is a good normal reading and when should I begin to worry?

Thanks in advance for the information.

0 is the best reading.

If you are using and RODI unit, your reading should be zero ppm.

anything below .9 is cool but as you get closer to zero the better
