Orange Crush Soda syrup testing equipment

Antique Hydrometers, Beaker, and what I think is a thermometer? for testing the syrup used in soda fountains.

The delicate glass rests snugly in a green velvet lined case. The case itself is in top notch condition for being over 100 years old. The latches and hinges have zero rust and the leather is in superb shape. The leather handle appears to be original and is still very soft and pliable.
