## Questions & Answers

**Q: What exactly am i getting here?  the model # shows r-0002a with description of 2.75oz while the picture on amazon shows r-0004 with 2oz?**
A: Thank you for your question. This item's descriptive data is currently all messed up. I reported it to Amazon several days ago and it remains a disaster. This item is supposed to be a Taylor R-0004 reagent in the 2 oz size (a.k.a. R-0004-C). There is no "2.75 oz" size available and this is NOT a DPD reagent. it is a pH Reagent.

**Q: Can this be used to test drinking water?**
A: This reagent is for use with a Taylor test kit, such as the K-2006 FAS-DPD chlorine test kit. If you have one of those, or at least the pH comparator tube (the one with the colored windows to compare the color of the test water to), then yes, you can then use this reagent to find the pH of drinking water (if it's between 7.0-8.0). If the test water is out of this range, then no.When used with the Taylor K-2006, you can measure the pH in 0.2 increments (from pH 7.0-8.0).

**Q: how many drops per 10 ml ?**
A: Hi 5drops per 44ml

**Q: Can you tell me the expiration date**
A: 04/17

### ⭐ Review
*by D***S on 13 March 2021*

I am the 4th reviewer to have recently received a 0.75 oz bottle even though the product description clearly states that the product offered is a 2 oz bottle including a photo of a clearly identified 2 oz bottle. I have returned the product to Amazon for a refund. I would like to write it off as a mistake, but the fact that at least 3 others have received the small bottles makes me suspect that it is more than a mistake.
