Rudolph, Temperature Consultant
A new web site contains a brief but excellent
summary on just what
emissivity is in terms that the average technical person can understand.
He even gives some very practical advice on how to get a quick estimate of the
emissivity value if you do not have a clue. Please remember, you must measure
carefully and because we have no control over how careful you are or how well
you follow his advice, any errors you encounter are your responsibility not Rudy's
or ours. Things are not always as easy nor as simple as some brief suggestions

A new supplier of low cost, compact radiation thermometers

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 the business ethics and
technical abilities (and that of the organization they represent) of someone selling
these types of measurement devices.
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!!
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
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 2005. 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 not published in 2003 as part of the Symposium Proceedings; too bad.
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.
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. Two Technical Recommendations have been published b SPRING and are available on their website. They are open for comment and sometime in 2005, may become official standards in Singapore with due considertions for any received comments.
