luosh 3 Pieces Alcohol Meter Hydrometer Tester 0 to 100% with Thermometer Gadget Case Kit for All Spirits/Distillates, Whiskey, Brandy, Vodka etc.

I purchased these to replace a couple of kits that were damaged by my students previously and I wanted some that provided better protection of the hydrometers when not in use. These are pretty well protected, but the boxes are relatively light in construction so they will not stand up to a great deal of wear and tear. The hydrometers are fairly accurate and consistent in their measurement as long as you make the appropriate temperature corrections.For the money they are well worth the price and provide the measurements you need either in the lab or at your home brewing stations.
