Is there an alternative to digital thermometers?
liquid thermometer | ||
| Liquid thermometers are not as accurate as digital thermometers because they rely on the user to measure the liquid level, which cannot be broken down into such small increments as a digital thermometer. Glass thermometers, especially those filled with mercury, can be dangerous if broken, which is why they are no longer sold, but some older models may remain in people's homes. | ||
Infrared thermometers | ||
| Infrared thermometers are non-contact: they do not need to touch the object whose temperature they measure. This makes them best for large and inaccessible structures. | |
