## Questions & Answers

**Q: How often does this pH meter need to be re-calibrated and/or how can I tell when it needs to be re-calibrated?**
A: The manufacturer recommends keeping the device probe in a neutral storage solution; the protective tip case/container actually has a 'fill' line for guidance, and it is designed to hold a liquid safely when stored as indicated -- If someone uses distilled or deionized water by itself as a storage solution, the salts contained in the probe tip will dissipate and the probe will then need to be replaced--about $25, plus a fine headache trying to get it right. If you are out of storage solution keeping the probe wet somehow is better than dry--but don't store without the specialized solution for more than a day or so; these are typically $10-$13 for 100ml - 250ml size bottles on Amazon.

**Q: Can anyone confirm if this comes pre calibrated?**
A: Mine was, the PH20 unit. Dead on, but I still did the cal to know how. If you use it for pH 8.0 or lower, the 4.00 and 7.00 solutions are perfect-no need for 10.00 test buffer solution. I am AMAZED at how bad my cheapy meters are, and how they disagree with each other and this one.

**Q: Can this be used to analyze urine?**
A: Yes, it can tests urine with no problem. You can use the probe cap as a container for the urine.

**Q: I will be using this meter once a month. Do I need storage solution for the probe?**
A: Storing the probe in the storage solution helps keep the probe's sensitivity and accuracy. So it's a recommended practice. While storing the probe without any solution will not damage the probe, it's just going to cause the probe to lose its sensitivity and accuracy temporarily. Store the probe in the storage solution again for about 10 minutes, the sensitivity and accuracy can be restored.

### ⭐⭐⭐⭐⭐ Accurate, reliable, and perfect for professional kitchen use.
*by T***C on October 25, 2025*

I bought the Apera AI209 Value Series pH Tester for use in our professional kitchen, mainly to test the pH levels of barbecue sauces and hot sauces to ensure they stay below the required threshold for shelf stability. It’s been a fantastic upgrade from our old Dr. Meter testers, which were cheaper upfront but rarely lasted more than three months and were frustrating to keep properly calibrated. The calibration process with the Apera is a breeze. Unlike other brands that give you powder packets you have to mix with “clean” water (and good luck deciding what counts as clean), this kit comes with bottles of perfectly balanced calibration solutions; no guessing, no inconsistencies, and no cursing over cloudy mixes. You start with a solid, reliable baseline right out of the box. Readings are quick (usually within 5 to 10 seconds), and the included carrying case is surprisingly sturdy and well-organized. It's been dropped a few times already. I know this pH tester is marketed toward a wide range of uses, but for food safety applications in a commercial kitchen, it’s been excellent. It gives us accurate, repeatable results, and peace of mind knowing our sauces are safe and shelf-stable.
