Question:
During Shabbat is one able to use a non-electric kitchen thermometer to check the temperature of food or water for making tea?
Answer:
Hello,
On shabbos we generally do not measure things, unless it is needed for a mitzva use such as measuring a sick persons temperature. But unless there is a specific mitzva need, we don’t measure on Shabbos, even if there is no electricity involved.
Best wishes
