America’s first thermometer company, started in Cincinnati, OH in 1836, Palmer Instruments has steadily evolved products geared towards industrial supply and process measurement.

From development of the “Foster Cup” thermometer in 1880, through the radical improvement of legibility by the patented “Red Reading Mercury” tube in 1929, to today’s temperature and pressure measurement innovations, Palmer has maintained the “first” tradition by bringing instrument value, service and quality to many industries.
