Electronic thermometers can be inserted in the ear to quickly register the body's temperature.

It's not necessary to use web sites, charts, thermometers, or anything else.

These special thermometers will allow you to chart slight changes in your body temperature, which indicate ovulation.

These watches are available with options like altitude memory, barometers, compasses, thermometers and more.

Available with thermometers, barometers and compasses, the Pathfinder is a great tool for the man on the move.

Perhaps better known for their talking thermometers, Voice Zone has been a familiar brand for hearing impaired people for many years.

The watches are another phase in their product line, but still offer the same functionality of the talking thermometers.

You'll also need two thermometers to take the temperature of the lye mixture and the fat mixture.

The paddle was driven by weights, and the temperature of the water was observed by thermometers which could indicate 2 kuth of a degree Fahrenheit.

From 1879 to 1888 he was engaged on difficult experimental investigations, which began with an inquiry into the corrections required, owing to the great pressures to which the instruments had been subjected, in the readings of the thermometers employed by the "Challenger" expedition for observing deep-sea temperatures, and which were extended to include the compressibility of water, glass and mercury.

The white line of enamel, which is seen in some thermometers behind the bore, is introduced before the mass of glass is pulled out.

In modern thermometry instruments of extreme accuracy are required, and researches have been made, especially in Germany and France, to ascertain the causes of variability in mercurial thermometers, and how such variability is to be removed or reduced.

In all mercurial thermometers there is a slight depression of the ice-point after exposure to high temperatures; it is also not uncommon to find that the readings of two thermometers between the iceand boiling-points fail to agree at any intermediate temperature, although the iceand boiling-points of both have been determined together with perfect accuracy, and the intervening spaces have been equally divided.

Special glasses have therefore been produced by Tonnelot in France and at the Jena glassworks in Germany expressly for the manufacture of thermometers for accurate physical measurements; the analyses of these are shown in Table III.

In the course of his inquiries he also noticed that different bodies in equal masses require different amounts of heat to raise them to the same temperature, and so founded the doctrine of specific heats; he also showed that equal additions or abstractions of heat produced equal variations of bulk in the liquid of his thermometers.

The measurement of temperature in the depths, unless a high-speed waterbottle be used, involves stopping the ship and employing thermometers of special construction.

Since 1870 thermometers on this principle have been in use for regular observations at German coast and light-ship stations.

All thermometers sunk into deep water must be protected against the enormous pressure to which they are exposed.

If the plate is thin, it is necessary to measure the thickness with great care, and it is necessary to assume that the temperatures of the surfaces are the same as those of the media with which they are in contact, since there is no room to insert thermometers in the plate itself.

The actual tempera ture of the metal itself can then be observed by inserting thermometers or thermo-couples at measured distances from the centre.

The chief difficulty in this method lay in determining the effective distances of the bulbs of the thermometers from the axis of the cylinder, and in ensuring uniformity of flow of heat along different radii.

C. Mitchell, under Tait's direction, repeated the experiments with the same bar nickel-plated, correcting the thermometers for stem-exposure, and also varying the conditions by cooling one end, so as to obtain a steeper gradient.

They are also partly caused by the large uncertainties of the corrections, especially those of the mercury thermometers under the peculiar conditions of the experiment.

The gradient near the entrance to the calorimeter was deduced from observations with five thermometers at suitable intervals along the bar.

An additional difficulty arises in the case of observations made with long mercury thermometers buried in vertical holes, that the correction for the expansion of the liquid in the long stems is uncertain, and that the holes may serve as channels for percolation, and thus lead to exceptionally high values.

The amplitudes and phases of the temperature waves at different points are observed by taking readings of the thermometers at regular intervals.

No allowance was made for the variation of density with temperature, or for the variation of the distance between the thermometers, owing to the expansion of the bar.

The original intention was to push the experiments to a pressure equivalent to thirty atmospheres, but owing to the signs of failure exhibited by the boiler the limit actually reached was twenty-four atmospheres, at which pressure the thermometers indicated a temperature of about 224 0 C. In his last paper, published posthumously in 1838, Dulong gave an account of experiments made to determine the heat disengaged in the combination of various simple and compound bodies, together with a description of the calorimeter he employed.
