Which thermometer is more accurate?mercury or non mercury?

Answer 1

The most accurate are electronic ones.

Answer 2

Although certain applications may continue to require slightly higher accuracy and precision of a fine mercury thermometer, most lab needs can be satisfied with non-mercury thermometers. All of the non-mercury thermometers proposed meet accuracy standards from the National Institute of Standard and Technology (NIST) and Deutscher Kalibrierdienst (DKD). If your application cannot use a non-mercury thermometer then we will ask that the thermometer be Teflon coated to prevent spills when broken. We can assist you with information either on purchasing Teflon coated thermometers or coating existing mercury thermometers.

Answer 4

I'd still use it as long as I'm confident that I could keep it from getting broken. If it's stored so that only adults could get at them, and you're careful when you're handling it, it's hard to argue against continuing to use it. The old mercury thermometers are accurate, and perfectly safe as long as they don't get broken. On the other hand, once they are broken, loose mercury is nasty stuff. If you have small kids visiting, though, it may be best to ditch the thermometers. There's a risk they'll do something to break the thermometer. Unfortunately, free liquid mercury is unthreatening, pretty to look at, fascinating to play with, and seriously poisonous over time, and kids if unsupervised will likely do things like play with it or worse eat it thus drastically increasing their exposure.
