Ok so to close the loop on this… After explaining to the retailer that the unit took ages (several minutes) to fix on a reading (smiley face), they sent me a new unit. I’ve been using it for a couple of months now after the initial calibration, and it’s been fine. It definitely fixes on a...

I wonder if it's my calibration solutions. I left some in the purpose made Apera holder (with the lids on). The pH 4 calibration was way off (can't remember the number, but the probe locked on something that was more than 0.4 away from 4.0), so I tipped that out and poured in some fresh 4.0...

Ok well both the retailer and Apera tech support implied this was normal. Here’s what Apera said: “For High-Accuracy measurements (≤ ±0.02pH), the meter should be calibrated before test every time; For general-accuracy Measurements (≥±0.1pH), once calibrated, the meter can be used for about a...

Yep, it's submerged to the line on the cap, and yes I do wait for the smiley. Mine sounds like the same model as yours (pH/EC/TDS/Sal/Temp) Maybe I need to send it back for a check...

To other owners of the Apera PC60 meter... I purchased mine about 6 months ago, as well as the Apera 3 point calibration kit. I've followed the manual, and stored the probe in the provided solution when not in use. I've also used the provided (and then my purchased for 3 point) calibration...

Sorry I may have mis-represented them. Forum rules don't allow me to link to their site, but they say that whatever chemical mix they use allows them to run a pH between 7 and 8.5, though they generally allow it to drift up to 8-8.5, all while allowing sanitation and no scaling, crystal clear...

Here in Australia we’re just getting into summer and pool season, so I’ve started checking things more carefully and adding salt, acid etc. There’s a company here that’s been around for a few years, who (amongst other things), promote a proprietary method of sanitation that doesn’t involve...
