Non-mercury thermometers have scale divisions equal to mercury thermometers. Most range from 0.5° to 1° C. Accuracy limits for non-mercury thermometers below 150° C are also compatible with mercury thermometers; accuracy is typically ± 1° – 2° C.
Beside this, are glass mercury thermometers still available?
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.
Moreover, can you suggest alternatives to mercury thermometers?
(c) Other alternatives to mercury thermometers are Digital thermometers and Spirit thermometers.
Can you use any thermometer for basal temperature?
