Hohmann & Maurer Temperature and Pressure Gauge

Description
This is a short-stem instrument designed for industrial use. The brass plate at the top of the V-shaped iron case is marked “HOHMANN & MAURER / 90 / FULTON ST / NEW YORK / 1121.” The brass housing around the mercury-in-glass thermometer is graduated, on one side, from 140 to 274 degrees Fahrenheit. The other side is marked “HOHMANN & MAURER / 90 / FULTON ST. NEW YORK” and has a scale from zero to 25, presumably for pressure in pounds per square inch. This was probably made in the mid-1880s, shortly after the firm began in business in New York City. It came to the Smithsonian in 1923.
