Comment on PH measurement
gigachad@sh.itjust.works 4 days ago
When I left university, which is like 6 years ago, we used distilled water. As tap water does not usually have a pH of 7 but cab vary between 6.5 and 9 (depending on location), it makes absolutely no sense for me to use it for rinsing. However this may depend on your device and application, as for household level like measuring plant water or something tap water could be sufficient.

Exactly. Thanks. This is a ‘non-domestic’ application shall we say. Measuring something with any buffer capacity at all should negate the water’s pH, so shouldn’t be a problem, but the manufacturers advice still doesn’t sit comfortably with me. But they should know!
