PH cal

[clone]

does anyone have #7 calibration. I need to either barrow/buy some fluid. I have some older fluids and im hoping its that and not a bad probe.

If you can't find any calibration fluid, fresh RO/DI with TDS at 0 will have a PH of 7.0.

I have some Kevin, you just have to drive out to Bulverde to come get it.
