AI1205 PH60S-E Replacement Probe for PH60S Spear pH Tester, Also Compatible with PH60, PC60, and PH60F

Best, affordable pH meter out there for the food hobbyist. My last probe lasted a year and was getting difficult to get a good calibration so ordered this new one. Easy to switch out and calibrated right up. I'm probably good for another year. I do charcuterie and also lacto fermentation. That's what this meter was designed for. Be great for cheese making and sourdough also.Now the few people who left bad reviews. Several said don't use on soils. Absolutely right, using this for the wrong application will ruin the spear probe in no time. This probe is for FOOD, not solid or course materials like soils. Proper care, cleaning and storage and it will stay reliable for quite a while.

I'm a baker and use this to check the pH of my sourdough cultures and the dough as it develops. It's very easy to use and gives a quick reading with compensation for the temperature.My only issue with it is that it has to be stored upright so that the tip is always in contact with the KCl solution. I wish they would design a better cap for it so that it could be stored horizontally.

Only 4 months later my ph tester no longer works. The ph never fluctuates and is stuck at 7.0 no matter what. I have tried to calibrate it with Apera calibration fluid and properly stored with KCI storage solution.

This product uses a long, delicate, glass shaft, which easily breaks. Especially if you’re trying to probe something.

Had mine for about 4 months and now all it says is -2.00ph and won't calibrate I had to put the original back on do not use this for soil it breaks very easy

Had it a little over a month, only used as recommended and now it won’t calibrate..

They things breaks. Don’t use for checking soil.
