How accurate are glass mercury thermometers?

How accurate are glass mercury thermometers?

The accuracy of a typical glass thermometer is ±1 scale division. These are available in partial immersion or total immersion types and typically have to be considerably longer to achieve the same specifications as a mercury thermometer.

Are mercury thermometers most accurate?

But mercury thermometers also have real advantages over the alternatives. They’re often cheaper and more accurate, especially at higher temperatures. And unlike one common alternative, electronic thermometers, they’re self-contained (no wires sticking out) and require no power.

Are glass thermometers more accurate?

Both laboratory and clinical studies show that there is no significant difference in the average accuracy of the two types of thermometers, however there is a greater fluctuation of readings of temperature when using electronic thermometers.

Do mercury thermometers lose accuracy?

In an ideal condition, the results are accurate. Many people think it inaccurate mainly because they use the instruments in the wrong way. There are too many factors affecting the forehead temperature, including room temperature, skin dryness, and more.

Are glass thermometers more accurate than digital?

The digital thermometer is not only faster on body temperature measurement results providing, but also better accuracy results to us. Based on the tested records of the experiments, the accuracy of a digital thermometer could be 0.1℃. The accuracy is better than the normal mercury thermometer.

Which thermometer is better mercury or digital?

1. Digital thermometers provide faster results. Digital thermometers provide fast results as opposed to mercury thermometers whose readings are slower to realize because you have to wait for the mercury to heat and then slowly rise to display the temperature.

Which type of thermometer is most accurate?

Digital thermometers
Digital thermometers are the most accurate way to measure body temperature. There are many types, including oral, rectal, and forehead, plus many that are multifunctional. Once you decide on the type of thermometer you want, you can think about design, extra features, and price.

Which thermometer is best mercury or digital?

Is a mercury thermometer more accurate than a digital thermometer?

Which thermometer is best digital or mercury?

How do I know if my thermometer is accurate?

Insert the thermometer stem at least an inch deep in the ice water without letting the stem touch the glass. Wait for the thermometer to register; this usually takes a minute or less. The thermometer is accurate if it registers 32° F or 0° C. (My three thermometers are within 1 degree of accuracy at this end.)
