What Will Replace Them? The National Institute of Standards and Technology (NIST) announced last week that it would stop calibrating mercury thermometers starting March 1 a move that brings the U.S. one step closer to phasing out these temperature-measuring devices for good.

What happens if you break a mercury thermometer?

If you break a mercury thermometer or light bulb, a small amount of liquid mercury may spill out. Liquid mercury can separate into small beads, which can roll some distance away. The mercury may also evaporate into vapour. However, this small amount of mercury is extremely unlikely to cause problems for your health.

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.

How accurate is a mercury thermometer?

For thermometers that have a high range of 260° C, accuracy below 100° C is ± 1°-2° C for both mercury and non-mercury thermometers. Above 100° C mercury thermometers have an accuracy range of ± 1.5° C, while non-mercury have an accuracy limit of ± 3° C.
