Apera Instruments AI1201 pH Tester, Probe for PH60 Pocket

All ok,

I can’t fault the functionality of this probe, the first lasted two years, before it got slow and wafty. It was the flat probe. But seeing as they are impossible to get and have pretty much doubled in price since my original purchase, I opted for the standard probe here.This I was also lucky to buy for £28 before the recent £10 increase. Which if I remember rightly was also about £8 more than the probes were when I first bought the meter. I can’t see the justification for this, what overheads have increased soo much that this company feels the need to double the price of the replacement probes in just two years.

Didn’t screw the probe tight on a brand new unit and it got wet inside. Bought a new probe, hoping the main body electronics weren’t damaged. Installed new probe making sure it was tightened this time. It calibrated easily. What a relief. Lol

Purchased the new tip to replace one that had aged out. Once calibrated, it gives me what I believe to be a very accurate reading of the PH level in my well water.

Nach 9 Monaten ließ sich mein Apera ph 60 nicht mehr kalibrieren. Ein Austausch der Sonde brachte Abhilfe. Nun funktioniert es wieder sehr genau.

Could no longer calibrate and get effective pH readings. Replaced and calibrated, now the unit works properly.Do not rely upon an older probe!

I had to replace a faulty probe for the PH60. The original probe lasted 3 years and was solid. I did drop it a few too many times into the bucket. I never checked the seal and the last time I did it, I found out it leaked a bit and shorted the probe.In any case, this replacement is a newer model and has a probe guard which I'm not pro or against. I haven't noticed it is any different but it can be removed if you don't like it. I removed it on the PH20 model that I also have.
