A poll what does this thermometer read?

[jon_berzerk]

Where are you getting all these readings? Doesn't it say 39 degrees? I've already got trifocals. Can't do any better than that.

i see it sitting on 38

the little hash marks represent 2 degree increments

i dont see the red line 1/2 past the last hash and 40

maybe it is

 

[jon_berzerk]

looks like about 38.5 degrees

According to the hand book for weather observers, the last fully covered tick mark is the correct reading to notate.

My vote is 38 degree's... Even back then they knew that these devices had limitations on how accurate they are..

yup

The Sort of Sad Death of the Mercury Thermometer

I have collected Mercury by the half bucketful. It's an amusing thing to put on a heavy rubber glove, make a fist and try to see how deep one can push it into the Mercury. (Hint, not very far at all with out an awful lot of effort.)

How did you get into the position to collect mercury? And where from? Seems a rather interesting and strange thing to do.

lol Damn dude, one time at work a mercury switch busted apart ( I never seen one do it before) mercury was all over the ground , I am like to my boss " how the hell am I supposed to clean this up? We ended up chasing around mercury balls for a bit untill we got a dry vac (with a plastic double plastic bag.

Taking a simple unscientific poll what does this thermometer read? Pretend you are a scientist in 1902 and have to read and record a thermometer every day.

And where is your 1902 calibration certification?

A bucket of water filled with ice cubes.... let set for about 15 min and read. it should read 32 degree's F or 0 deg Celsius...place that date and time of check on the station log form with the reading observed.

Even back then they understood the tools they were using...

that is one method of calibrating a thermometer

38.8 degrees

However that's not the point. It makes no difference really. As long as the person reading it is being consistent.

sure it does over the course of time

i see it as 38 you see it as 38.8

so for the first year i measure it daily and get 38

you come along the second year and measure 38.8

low and behold the temp went up .8 from the previous year

 

[bodecea]

My AGW friends think it reads 80 degrees F.

Cool story, bro.

What is the other ('s)?? Just always thought mercury thermometers were calibrated by a ice bath?

Don't get me started on how company's rip people off on field calibration of digital (and software) temperture controllers for ISO9000 certification.

any source of a known temp to set it by

ice water is the easiest

A bucket of water with ice in it can be anywhere from 32.1 to 50 degrees F.
Second issue is the purity of the water. Water with high mineral content will freeze at a different temperature than pure water.

Learn something new everyday. So how the heck do we know What the real temperture is? If it was always measured wrong ?

Now it sounds like measuring electricity with electricity with a volt meter.

Today we have specialized calibration equipment tied to an industry standard. But a hundred years ago they got close at best.

I don't think a purported variation of 17.9 degrees represents a controlled condition. For that matter one can have ice in water at 100 degrees.

thermometers matched to a precise and uniform standard under controlled conditions.

It reads 'you're not spending enough money on your weather stations you cheapskates'. Don't buy Walmart thermometers for accurate recording of data. No wonder you don't trust your scientists.

38.95

But it all depends on what part of the scale markings it was calibrated to. That is basic. I guess it's a bit sophisticated for the plastics industry which doesn't seem to understand the concept that many measuring devices in science must be calibrated to be of use.

i think it shows 38.96

True on the consistent part.

What we're looking for is change. Change up or down. Okay, we don't have massively accurate readings in the past, and now we have more accurate readings in some parts of the world and less so elsewhere.

That doesn't mean data from the past is not worthy of being looked at. It just means that people need to be aware of the fact.

We still don't have 100% accurate reading of temperature. However the consistency can tell us a lot about the changes in temperature.

well the facts are if you couldn't read it back then, you certainly can't read it today or are you George Orwell?

Lab teching at a pulp and paper mill, collected from the Mercury trap of the Cl2 plant.

 

[mamooth]

Was there any point to this thread, other than that bear and the other deniers are failing hilariously at basic statistics, failing so badly that they don't have any idea of how badly they've failed?

That is the point everyone else is taking away from it.

You denier loons stink at the science, and that's why you're laughed at. It's not because of a socialist conspiracy. It's because you're incompetent cult clowns.

Duh. Thermometers can't read...
