What is another word for Caesium Clock?
Pronunciation: [sˈiːsi͡əm klˈɒk] (IPA) 
A caesium clock is a highly precise atomic clock that uses the vibrations of atoms of the element caesium to measure time. However, there are other types of atomic clocks that use different elements, such as rubidium, hydrogen, and mercury. These clocks are often referred to as rubidium clocks, hydrogen maser clocks, and mercury ion clocks, respectively. Additionally, there are other types of highly accurate timekeeping devices, such as quartz crystal clocks and GPS clocks, which rely on different technologies. While these clocks may not be referred to as caesium clocks, they all serve the same purpose of accurately measuring the passage of time.
