Thermo Dial Laboratories primarily made figural desktop thermometers. They were sold as paperweights and of course, used to measure the indoor temperature. This had a different use. It was used in hospitals in the early 1900s to make sure blood was at the right temperature for a blood transfusion. This thermometer was set in a cabinet that stored the blood in bags. You can see there is a mark right below 100 which reads BLOOD HEAT. The thermometer is in good vintage condition. Please take a moment and look at the photographs.

The thermometer is metal with a cast iron bottom covered with painted copper. This is truly a unique thermometer. It stands 5 inches high, and the base has a diameter of 3 ½ inches. This would look great on your desk or on a shelf. It would make an interesting paperweight. Enjoy!
