Apera Instruments, LLC AI313 Pocket Tester, PH60S, Premium Food, Swiss Spear Sensor (Replaceable), 0.01 pH Accuracy, -2.00-16.00 Range

The readings settle quite quickly and the built in temperature element corrects the pH for temperature saving that extra step. The instrument is robust and feels well made. I am pleased with it.

It's made my formulation experience a breeze!

So I went through (or tried to go through) the calibration procedure on receiving my PH60S. It refused to calibrate, with the reading continually jumping round by over a hundred times it's claimed accuracy. I went through the troubleshooting guide - no joy, so raised a support issue with their main office in the USA. They handed the issue over to Germany, who handles support & warranty issues for Europe. They just advised me to return it, as the import/export duties to get it repaired or replaced (they have no service centre in the UK) would have been about £30 each way - so approx £60 for a warranty replacement. So I returned it & will buy an alternative from a supplier that can properly support UK customers.

Un aparato fiable y facil de usar. Basta introducirlo en un liquido o sólido para saber inmediatamente el PH.

I bought this to improve my sourdough bread baking. It’s a lot of money for this application, but it’s my hobby, and it has really paid off. The pH of sourdough starter is a great gauge of its readiness for baking. It’s also a very reliable gauge of how quickly the dough is progressing through the stages of fermentation before you make the critical decision to shape the loaf and start the proofing stage. Through the seasons, the timing changes with room temperature. Winter sees slow fermentation, and hot summers accelerate it. Timing by the clock is unreliable. This is where pH comes in. The pH meter allows me to hit the right spot every time. It makes it even easier by adjusting the displayed pH reading to account for temperature differences. This meter is convenient, easy to use, and consistently accurate. It makes my baking a lot easier.

Le PH mètre APERA est de très bonne qualité, la mallette est très pratique. Il est facile d'utilisation. Je ne mets que 4 étoiles car la notice n'est pas en français. Je l'ai entièrement traduite en français. Je recommande

Die Handhabung ist gut verständlich. Ich nutze das Gerät, wenn ich z.B. Tomaten einkoche. Diese sollten einen bestimmten PH-Wert haben, damit keine Gefahr für Botulismus besteht.
