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. ## Frequently Bought Together - APERA INSTRUMENTS AI209 Value Series PH20 Waterproof pH Tester Kit, ±0.1 pH Accuracy - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - Apera Instruments AI213 Value Series TDS20 Waterproof TDS Pocket Tester kit, Accuracy: ±1% F.S, 2-Point Auto.
