Why Choose Palmer Wahl?

Six Reasons to Choose Palmer Wahl Instrumentation Group

Who We Are

We are your single best source for a wide variety of temperature, pressure, humidity, test and calibration instruments, offering many years of experience and leadership in manufacturing quality instruments. We have developed many unique features and patents which have been incorporated into our product line over the years bringing you an extensive line of process measurement, test and calibration instrumentation.

Our Reputation

Since 1836 we have carried on a tradition of over 187 years of continued innovation. Palmer was the first thermometer company in the United States, and invented the “Red Reading” Mercury Thermometer. Wahl developed the first portable digital platinum-RTD thermometer system and the first miniature temperature recording label.

The Palmer Wahl Advantage

Because we are manufacturers, we control the quality and configuration of our instruments. We provide instruments with customer specified configurations and required calibration. We maintain manufacturing and quality assurance systems to ensure every component is assembled and figured properly. The result: Quality instruments ready to use upon receipt, with “Total Customer Satisfaction”.

Traceability to National Standards

We design and manufacture our instruments to the most stringent quality standards. Some of which include: Military Inspection Requirement MIL-I-45208A and Calibration Requirement MIL-STD-45662A. Where required, instruments are thoroughly tested with customer requested configuration and/or calibration, traceable to NIST. We provide many of our instruments with both certificates of traceability, and test records which prove accuracy compliance. We provide certified, traceable calibration data which meets ISO 9000, FAA, and FDA quality standards.

Engineering Quality that Makes Sense

Built-In Quality is easily visible in every Palmer Wahl product. For example, machined, cast, or molded cases have a solid feel in the hand. Graduated scales, printed dials, or digital read-outs give crisp, highly visible readings. All switches, keypads, and machined surfaces have that “finished touch”, demonstrating our superior product design. Our ergonomic, easy to use and read designs make our products functional in the field.

Affordable Value and Service

We offer a large selection of instruments to suit every budget. Our repair and re-calibration services carry the same high priority as any new instrument. Our Customer Service is dedicated and experienced, and can provide you with technical information, or help with technical problems.


Everyone I have spoken to at Palmer Wahl was very professional, and honest, if they were not able to assist, they made sure someone with that knowledge assisted us.

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 contacted Palmer during the shut down in need of emergency parts. They went out of their way to speak to others in the plant in order to get us the items that we needed. So together with others that helped out, we were able to get our parts shipped out the same day and to our customer the next day. We are in Canada as well, so it was an international expedited order. Great customer service!!!!

Recently a customer placed an order for temp-plates and they ask that we “PLEASE SHIP AS SOON AS POSSIBLE”, they were quoted a delivery date of 8-25-2017. The customer then called and ask, “Also would it be possible for me to change the shipping address? If PW can ship directly to our remote site, it will save a day on our end”. Our staff here at Palmer Wahl worked hard to get the order ready and shipped, the order was sent on 8-21-2017 by FedEx express. Below is their testimonial.

“Thank you very much, this is why I love Palmer Wahl. Y'all are great!”

Have a great day!
