I'm using the Sense & Dispense system with a Goldine Pro-Logic controller. The reading of the pH in the test cell of the Sense & Dispense does not agree with the pH reading I get in the pool.
The test cell reads less than the pool, usually about 0.2 ppm less.
Is this normal? Can this be corrected? Any ideas to have the same pH reading in the test cell as the pool?
Thanx for your help.
