Ph reader

[Walter2050]

Thinking about purchasing a Apera60 ph reader . It come with 4.0 and 7.0 calibration solution. If my pool ph is 8ppm or higher will I need a different calibration solution?

Get the pH 10 calibrating solution also so you can do the 3 point calibration.

Calibrating between 7 and 10 is what we need for pools. 4 is of no value.

My apera ph60 came with all three solutions. Don't they all?
