We have 4 Trojan T105's on our sailboat. Our previous battery electrolyte tester was too small.I know from experience to flush this item with fresh water after each use.Very pleased.

This tester isn't the best I've ever used but it will work and get the job done. The markings are a little hard to read depending on the light. I bought this to replace my tester that I've been using for over 35yrs and finally cracked beyond repair. If this tester will last half that long it will be doing good.
