America's First Manufacturer of Precision Industrial Temperature and Pressure Instrumentation

Our History

Palmer Instruments, Inc.

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 the 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.

Wahl Instruments, Inc.

America's most innovative thermometer company was founded in 1953. Wahl Instruments, originally based in Culver City, CA, was formed to manufacture precision temperature instruments for industry.

Since then, Wahl Company Photo developed the first portable digital platinum-RTD thermometer system and the first digital universal soldering iron tester to prove government compliance standards. Wahl was also the first to bring the industry a  portable, non-contact, handheld infrared thermometer at an affordable price point,  without sacrifice in accuracy and reliability.

Wahl is also recognized for developing and patenting the first miniature temperature recording label. This useful, inexpensive and accurate product is found in thousands of maintenance applications throughout the world today and is credited with the creation of an entire industry grown in its path. Not content to be solely a pioneer, Wahl remains a  leading manufacturer of all these products.

Excellent response time; provided complete and thorough support for exactly what was needed.

We are very pleased with the performance of the new transmitters. They have smoothed out our chart recorder trace lines which makes looking for deviations in cook temperatures much easier and more accu- rate. They are an improvement over what we had in that regard and have become the Certified Standard for our old plant.

"We are currently using the DST400 series thermometer in a pipe thermowell to verify ice cream temperature as it is running. Knowing the temperature of the ice cream is crucial for achieving a quality product. We chose the PalmerWahl brand for its accuracy and dependability, customer service was very helpful when deciding which model would work best for us and in expediting the order. The calibrating software seemed complicated but was extremely easy to use. We are very satisfied with our purchase and I would definitely recommend PalmerWahl thermometers to anyone looking for a quality thermometer."
