955:. Thank you for your concern. Yes, the article is overloaded with part repetition, and even confusing, and could do with improvements. If you find things in it that are "probably erroneous", please identify them, settle whether they are actually or just probably erroneous, and get them corrected, all by use of reliable sources. Quite likely there are erroneous things in the article. Much in Knowledge (XXG) is erroneous.
1009:; indeed, I suppose that all physically reasonable absolute temperature scales are so. But by that criterion, there are notable temperature scales that are "physically unreasonable". In particular, there is no general way of relating empirical temperature scales precisely affinely to the absolute scales. Material thermometric properties are often nearly but rarely precisely so. Much practical thermometry is empirical.

There are many names for scientific thermometers. Using a table of contents that lists types of devices by name rather than calling each a thermometer doesn't support your argument. The third book link has 6 chapters titled by type of thermometer. Thermocouples, for example, are in the chapter titled
867:
There are a few references to manifolds in this article, i.e. "Hotness may be represented abstractly as a one-dimensional manifold." In this context, it seems like this introduces unnecessary jargon, and is less precise: there are only two one-dimensional manifolds, the circle and the real line, and
931:
All physically reasonable temperature scales are related by affine relations of the form T' = a T + T0. I believe the article should only mention the
Fahrenheit and Celsius "relative scales" (i.e. defining a 1° difference) and the Kelvin scale (absolute zero at 0, same 1° difference than Celsius).
1214:
There may be some confusion about the physics here. Satellites don't measure temperature directly. They do not use temperature sensors, except for monitoring themselves. Instead they measure incoming radiation at various wavelengths and, assuming a model of how the radiation is produced by the
1259:
As for the sentence in the lead paragraph, I suggest "measured with a thermometer or by other means." This is comprehensive enough that it covers any sort of device or method of determining temperature, including those model-dependent satellite measurements of the earth's temperature.
1034:
This wikipage is way too talky and mentions a lot of irrelevant stuff. Is it really necessary to include a graph of the human body temperature over the course of a day and various temperature scales before giving a formal definition and description of what temperature comes from?

with: "In
Newtonian mechanics, momentum (PL: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object." It isn't unreasonable to demand one sentence with a more scientific definition.
1235:. I would say that any device that reads out a result as temperature is considered a thermometer. If the output is radiation readings that need computer processing elsewhere, then it isn't a thermometer. But that is just my opinion on where the field is going.
1245:, then has a section on satellite temperature measurements. I would not merge the articles. Not all determinations of temperature are done using thermometers. It could be rewritten into the top-level article on the subject.
166:
894:. The literature contains discussions of temperature in terms of a hotness manifold. I haven't thought much about this, but I guess that so-called 'negative temperatures' can be seen as residing in the circle.
