Infrared Radiation Thermometer Vendors

Here's a partial list of some of the vendors of Infrared Radiation Thermometers, including spot, line-measuring (Line Scanners) and area-measuring devices (Quantitative Thermal Imagers) and related services such as calibration and user training. It is incomplete, we know. It does cover most of the prominent companies involved in the market and provides at least a starting point.

If you need or want to look elsewhere,there are always the various supplier directories not the least of which is Global Spec on the Web and the various directories at The ISA with its Directory of Instrumentation and Sensors Magazine, for instance.

Why do we include makers of Thermal Imagers along with IR Infrared Radiation Thermometers? A good question; one that is often asked. The reason is really almost apparent. Most of the Thermal Imager makers have instruments that report results in terms of temperature. That's it. They are area-measuring temperature sensors-whether highly accurate or inaccurate. Accuracy is not the criteria-measurement function or intent is.

Those highlighted sites have more than expected useful technical information. They are much more than an on-line catalog.

ThermoGauge Instruments - Precision Blackbodies

Editor's Note:(We think that this is worth repeating) Some vendors are more capable and/or honest than others, just like in every business. The watch words are, as always: "Buyer beware". Until you build up confidence in te business ethics and technical abilities (and that of the organization they represent) of someone selling these types of measurement devices.

There are no standards for the names of the spot-measuring infrared devices. Most metrologists that work in this field tend to call them "Radiation Thermometers". Could that imply, from the enormous variation in names of these devices, that standardization is non existent or not mature in the noncontact temperature sensor field? Yes, YEs, YES-there is room for a great deal of work in this area!! That is the root of the problem and, in our opinion, until that is resolved, it will hinder the growth of the market for these devices. Too many people have been "burned" by a misapplied instrument that they swear them off forever. That still happens despite the many great successes that have been achieved by correctly chosen and applied units.

Don't you get caught in the spec trap, thinking that you know what the specification on a data sheet means. Fact is there are not even any standards for the nomenclature used to describe technical features of these devices, starting with calibration uncertainty! Manufacturers know (we hope) but don't always tell all. Few agree in any aspect of their specifications beyond the temperature range of a given unit. The ASTM in the USA has brought some order to this with Standard E 1256, but it is voluntary and not required by many buyers, as of 2003. The German Engineering Organizations VDI/VDE have also published some exceptional information including an initial attempt to standardize the terminology used to describe the properties of Infrared Radiation Thermometers. A recent paper at the 2002 International Temperature Symposium from Germany described the VDI/VDE situation in great detail. See the Reference page for a more complete reference to the Symposium. It was published in 2003.

The lack of standards and precise nomenclature in terms of quantitative temperature measurement (called "radiometrically calibrated devices" by most of the suppliers) is an obstacle, in our view, that thermal imaging technology needs to overcome to master many of the more demaning uses such as human body temperature screening and process monitoring and control. The "Buyer Beware" caution applies doubly or triply with these devices simply because they are more complex than the single spot infrared radiation thermometers, there is much technical confusion and not a widespread understanding about temperature calibration and measurement with many of the traditional imager manufacturers. Most of their attention over the past decades has been in imaging characterization in terms of contrast.

The entry into the thermal imager market in the past few years by the top-tier radiation thermometer companies, who live and thrive on precision and accuracy of IR temperature measurement, may create some changes and improve this aspect of the business. In addition, one organization that has attempted to bring some order to the temperature measurement issue is the Infraspection Institute, one of the oldest and largest thermography training companies. They have had information on their website and that of their Symposium Group, IR/Info, on this issue for the last year, at least. More recently, The Standards organization of Singapore, known by the acronym SPRING, has been developing a Technical Standard for basic evaluation of thermal imaging cameras used in screening humans for possible elevated body temperature as a result of the SARS scare in early 2003.

Finally,if you have a requirement spelled out and are sure it is covered by current standards or by a set of detailed specifications you have developed, are you going to be using the sensor in a ISO900x production or a process or test that is critical? Then you will most certainly need a traceable calibration for the devices you seek. Without it any measurements will have errors that can only be guessed, not verified, nor ever verified or repeated except by happenstance. Often the last item on a purchase checklist is the most important, as is this one: Traceable Calibration. In their 2001 book, "Traceable Temperatures" (see our References page) Nicholas and White observe that measurements without traceabilty, are not measurements at all but effectively some vague effort that, in a critical analysis, is seen not worth the time and money.

That all implies, among other things that there is a test or demonstration of capability that a unit must pass to be accepted. Even devices that will be used to only compare two temperatures (measure a temperature difference) need to have some reference to which they can be re-tested to verify that they are meeting the requirement. Often simulating the need under true application conditions of measurent can be challenging and difficult to do and maintain a traceable calibration to within the desired norms.
