When you buy a thermometer for professional or home use, how do you know for certain that it reads accurately across its temperature range?
Houseware makers buy single-chip circuits and cheap sensors in bulk. While these components are economical choices for novelties and the addition of temperature readings to household clocks and the like, these components are not typically used in professional instrumentation. To make things worse, the finished products are frequently not calibrated for precise measurement. In the rare case that a manufacturer actually calibrates individual thermometers, how does one know for sure that they used the proper equipment, have the appropriately trained staff, or even that they maintain measurement traceability to national standards?
Unlike the consumer electronics market, the instrumentation industry relies upon an international standard of calibration lab accreditation to provide an independent, authoritative, and legal standard of recognition of calibration validity that spans borders. Calibrations performed by an accredited laboratory are legally recognized in most of the developed economies of the world. ISO/IEC 17025 is the standard for technical competence in calibration and testing labs.
ThermoWorks Calibration Lab
ThermoWorks is the only maker of food thermometers that operates its own in-house accredited calibration laboratory. A2LA (American Association for Laboratory Accreditation) evaluates the facility, the equipment, the quality system and the technical proficiency of laboratory staff and publishes an official scope of capabilities for the ThermoWorks lab that certifies our ability to calibrate instruments for specific measurement ranges and to certain levels of accuracy.
The ThermoWorks lab employs temperature baths with stabilities to ±0.001°C for accurate probe and thermometer comparisons. Our reference thermometer features a published accuracy to ±0.000015°C. When all uncertainties in our temperature calibrations are combined, ThermoWorks’ accredited scope assures calibration uncertainties better than ±0.005°C (±0.01°F). Humidity calibrations are also available with uncertainties to ±0.55%RH. Click here to view our full scope of capabilities.
Whether ThermoWorks calibrates an individual instrument or sensor directly in the accredited lab, or on the factory floor against standards that are themselves calibrated in the lab, our customers can be fully assured that a ThermoWorks thermometer reads accurately. ThermoWorks makes only professional grade instruments and is the only company in its field that goes to this length to guarantee precision.
If it says ThermoWorks on the box, you know you can trust the instrument.
Some Recent Customer Comments:
“Your Calibration Department does great work, and the calibration certificates and stickers keep auditors happy.”
“ThermoWorks answered quickly, understood my question on calibration and provided the document via email fast. Couldn’t be better.”
“They are prompt with recalibration—and advise of any costs prior to repairing. When I order new Thermapens, my order has always been shipped promptly. Friendly, helpful customer service.”

As a Quality Engineer with calibration of our machine shop gages as part of my duties, I have a better than average understanding of what your accreditation means to the quality of you product. My wife and I use our Thermopolis daily, and now I know for certain we purchased the high quality product we wanted.
Dan Forestiere says
Your ISO 17025 accreditation is what drew my attention to ThermoWorks and gives me confidence in your products. They are by far the best consumer temperature measurement devices I’ve ever encountered.
