For decades mercury thermometers were a mainstay in many testing laboratories. If used properly and معايرة correctly, certain types of mercury thermometers can be incredibly accurate. Mercury thermometers can be used in temperatures ranging from about -38 to 350 °C. The use of a mercury-ثاليوم mixture can extend the low-temperature usability of mercury thermometers to -56 °C. (...) Nevertheless, few liquids have been found to mimic the thermometric properties of mercury in قابلية التكرار and الدقة والضبط of قياس درجة الحرارة. Toxic though it may be, when it comes to LiG [Liquid-in-Glass] thermometers, mercury is still hard to beat.
an Italian weather station in العزيزية (ليبيا) measured a temperature of 58 °C (136.4 °F) on September 13th 1922. "Although this record has gained general acceptance as the world's highest temperature recorded under standard conditions, the validity of the extreme has been questioned."
"The Secretary of State, being a Minister designated(a) for the purposes of section 2(2) of the European Communities Act 1972(b) in relation to units of measurement to be used for economic, health, safety, or administrative purposes, in exercise of the powers conferred by that subsection, makes the following Regulations:
