## Questions & Answers

**Q: Does it measure ammonia , & other chemicals**
A: Hi, Dean!Thanks for reaching out. We know how sometimes those terms and water chemistry can be confusing. So what does a TDS meter detect?The term TDS, total dissolved solids, is slightly misleading. Not everything that is dissolved in water will be detected by a TDS meter. Only ions that have a charge can be measured with this technology. Pesticides and organic pollutants cannot be detected by a TDS meter. About AMMONIA - Science alert!The TDS meter will detect the ammonium in the water, but it is not possible to use TDS in place of a real ammonia test kit.Ammonia exists in two forms at the same time. Ammonia is NH3 and has no charge. Ammonium is NH4+  and has a charge. In water both forms of "ammonia" are present. Test strips measure both forms and report the level as a sum of both. Some kits call it Total Ammonia and some just call it ammonia. The test kits cannot distinguish between the two-the kits just total it up. I can explain how they do that but not in this message :)In acidic water nearly all of the "ammonia" is in the ammonium form. As the pH rises, some of the ammonium shifts to ammonia.  There is a ratio of ammonia to ammonium, depending on the pH of the water. If you have an aquarium, you should be using an ammonia test kit made for aquariums.Hope this helps! Have an awesome rest of the summer!

**Q: Is it good for testing ppm in grow rooms?  The water that a discharge?**
A: Yes it is!

**Q: Can this test the salinity in soups**
A: No. I assume you are interested in testing sodium levels? You can calculate that by the sodium level on the label. TDS is not the same as sodium analysis. You may be able to test for "salt", which is different than sodium level, with this kit. Here is an Amazon link. http://www.amazon.com/dp/B001DO35EU/?tag=jameslaytonco-20

**Q: Does it read water temperature?**
A: No just the ph is read with this meter
