Hanneman Direct Reading Specific Gravity Balance

Easy to use. Instructions are clear and understandable.

This is Dr Hanneman's specific gravity machine, it works just as good today as when made and if taken care of will last a lifetime, they are no longer manufactured but I am a huge fan. Now there is much cheaper much smaller specific gravity setups you can purchase, most used his design and adapted them and made them more compact etc. Sadly Dr Hanneman's tools are not being made any longer since his death and some of his tools are so easy and work so well for amazing prices. This is in my opinion yes a gemologist tool that you can use daily but it's more a piece of history by a revolutionary. I have seen variable pricing and for a new unused in box tool the pricing starts at $100.00 and goes to $300.00 so it is priced in mid range honestly it is large and don't recommend taking it apart and putting it back together over and over but left out in designated area. If you just want something to check specific gravity there is plenty of smaller not nearly as expensive lab setups for sale. This is in my opinion a piece of history but Dr Hanneman's my hero. My dream is to manufacturer his tools with modern technology to fulfill his dream of creating gemology tools that anyone could afford not needing to invest tons of money just to start exploring gemology.

Well its not totally as i expected quality ,fore the price it cost ,but it works and costumer service is okay to talk to

Easy to use Thank you
