America's first thermometer company originated in Cincinnati, OH in 1836. Since that time, Palmer Instruments has steadily evolved through product development  geared exclusively towards industrial supply and process measurement.

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