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.

Operating from a new facility in Asheville, NC since 1987, Palmer has  developed special-application products such as Dual-Sensing and "Slip-fit" thermometers, and pioneered new industry services such as free lifetime recalibration on pressure gauges. With the recent affiliation with Wahl Instruments, and resulting consolidation of manufacturing in Asheville, Palmer Instruments looks first to the future.
