I just downloaded the pdf of the complete report (in French). They tested the pH with a temperature-compensated Hanna probe, the alcalinity with sulfuric acid titration and the same pH meter (one assumes) and get this, the chlorine was tested DPD (not FAS but colorimetric) with a HACH kit! I wonder how they got that much precision out of DPD. Oh, and the report suggests that FAC be twice the amount of CC.

I wrote an email to the lab asking them, among other things, if they had tested CYA and ORP.
