Review: Great tool, great price...easy to use and understand - Worked well for monitoring/bringing back 6v batteries on my lift. Batteries were charging for 3days while I monitored the PH with this tool and was able to see it increasing daily vs assuming if batteries were improving. Let's you know if they'll hold a charge or if you're wasting your time charging. Use only "distilled" water if refurbishing/filling
Review: Perfect, Great value, perfect - Works very well. Excellent build quality. Ease of use and design is good. Able to use as a transfer from one cell to another. I squeeze the top slowly to absorb the material into unit. Extremely sensitive readings with this product which worked great for me. Do not breathe the fumes so this works very well in doing that. Be safe. Wash it up and put unit back into the package it came in. Awesome. Thanks

**Q: What is the expected life span of the rubber suction bulb on this Hydrometer?**
A: I have had my personal one for over nine years. This is Florida, humidity tend to be high and I clean it after every use. If you neglect it and leave grease or other residues on it the rubber will degrade and will not be able to do its job. It Depends on the care and environment where you operate. It is rubber after all.

Works great. Bought this new one since I was needing one. My old one got lost somewhere. Have used it numerous times now and I am not disappointed at all. I recommend this to anyone needing an over handy hydrometer around the shop.
