Using a Thermometer on Shabbat

Using a Thermometer on Shabbat
Day: Wednesday
Date: June 10, 2015
Parshat: Shilah
Yalkut Yosef: 328


It is permissible to take a person's temperature on Shabbat with a regular mercury thermometer. Liquid crystal thermometers, also called plastic strip thermometers, that display a number or change colors based on the person's temperature are also okay to use. Most disposable thermometers are liquid crystal thermometers. However, it is forbidden to use an electric thermometer except in a potentially life threatening situation, and even then only if there is no other thermometer around. It is permissible to weigh food for a Holeh She'en Bo Sakana if the doctor ordered that he do so. It is better to weigh the food before Shabbat. However, if he didn't do so it may done on Shabbat with a non electric scale.
