BRS Pharmaceutical Kalk Conductivity ?

[Johnic]

I remote dose kalk andmix up 10 gal of brs kalk and can only get 8 on the conductivity meter. I was under the impression I should be getting 10.
Does 8 sound correct ?

Depends on temperature and the accuracy of your meter.

But how do you know you are making it saturated?

Put a couple of tablespoons of powder in a cup of RO/DI and stir it for a while, what do you get?

Good idea. I’ll try that now.

Just did it and its reading 8 on the ec meter. I tested in salt water and it reads 9.9

Oh, it sounds like you are using a meter that cannot read higher than 10 mS/cm, and I expect the 8 mS/cm is just not accurate.

Correct, the meter can only read up to 9.9. So you feel the 8 is not accurate ? Should I buy new meter, and which one would you recommend ?

If the purpose of the meter is just to monitor kalkwasser, I'd take the 8 mS/cm as being saturated, and levels below that as being less than saturated.

Exact values aren't needed for most purposes.

@Randy Holmes-Farley I got a new meter and its still only reading 8 ms/cm ... is this the max or should when saturated by 10.3 ms/cm ?

Is it the same meter? What is its range?

What solution reads 8 mS/cm? A for sure saturated solution?
