Sentences with phrase «than the mercury thermometer»

In fact, Table 1 shows that for the last month of available parallel measurements the electronic probe (Tmax - Probe) often recorded considerably warmer than the mercury thermometer (Tmax - LIG).

Somewhat surprisingly, the automatic weather stations at Mildura for these three Septembers recorded statistically significantly cooler temperatures than the mercury thermometers.

Given electronic probes generally respond more quickly to fluctuations in air temperature than mercury thermometers, it follows that this method — instantaneous recordings from an electronic probe — would result in new temperature maxima under the same weather conditions.

Not exact matches

All told, the report says the program helped eliminate enough mercury to fill more than 480,000 thermometers, primarily because large purchasers, such as U.S. government agencies, bought computer screens lighted by light - emitting diodes (LED)-- a new lighting technology that does not employ mercury as did cold - cathode compact fluorescent lightbulbs of the past.

So, if you have two identical glass greenhouses with thermally isolated mercury thermometers at equilibrium in the sunlight [One with Air at Press =P, and the 2nd w / CO2 at Press =P], and you close the blinds — you will see the thermometer in the CO2 greenhouse retain its temperature longer — not because of any «global warming» type effect, but simply because Air conducts heat to the walls of the greenhouse better than Air does.

David, it's easy to see how a negative thermometer would work — you just have to have the glass expand more than the mercury.

So, if you have two identical glass greenhouses with thermally isolated mercury thermometers at equilibrium in the sunlight [One with Air at Press =P, and the 2nd w / CO2 at Press =P], and you close the blinds — you will see the thermometer in the CO2 greenhouse retain its temperature longer — not because of any «global warming» type effect, but simply because Air conducts heat to the walls of the greenhouse better than CO2 does.

As an ancient weatherman, I can truthfully state that every official mercury thermometer I used was quite easily read to the nearest tenth of a degree with no more error induced than plus or minus one - tenth of a degree.

How many mercury thermometers are accurate, or at least readable, to less than 1 degree C?

There are many more maximum temperatures measurements available for the electronic probe (n = 948) than for the mercury thermometer (n = 115), and the distribution is quite different, with a somewhat more normal distribution for the probe data, as shown in Figure 2.

Resistance thermometers used in industry normally had slower response than mercury in glass thermometers.

This is less than 1 percent as much mercury as found in old thermometers, but it still means broken bulbs should be treated with care and discarded bulbs should be recycled instead of thrown out.
