## 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.
