The main center of ensuring the accuracy of measurements in Ukraine with more than a century of history.
All the clocks in Ukraine are set by the time standard maintained by the Kharkiv Institute of Metrology. The seconds of this clock are counted at the atomic level, and its accuracy is so high that in 1 million 300 thousand years, the device can be only 1 second behind or ahead.
The Institute of Metrology was founded by the famous scientist Dmitry Mendeleev. He aimed to create a place where precise measurements could be conducted in order to discover the world and develop science efficiently. In 1901, Dmitry Mendeleev received permission from the Kharkiv governor to found the First Ukrainian Verification Trade Chamber of Weights and Measures in the city centre. Later, in 1922, it was transformed into the central metrological institution of Ukraine, the Main Chamber of Weights and Measures. At that time, the present building of the Institute of Metrology was erected, where researchers developed different physical measurement methods, new technologies, and measuring devices for decades.
The standards of different eras were kept here until recently: the 1-metre brass stripe — the standard of length till the 1970s; the gilded 1-kilo weight, which was the standard of weight in Ukraine since the early 20th century; the 1,0 Ohm (Ω) exemplary measure of electrical resistance, which was produced by the German firm ‘Otto Wolf’ in 1908, and the unique exhibit — the Riefler pendulum clock, made in 1925 in Germany.
During the years and decades, scientists of the Institute of Metrology created the first quartz clock resonators in the Soviet Union, the first pendulum clock for the country’s astronomical observatories, and the prototype nuclear metre of the magnetic field strength. The institute’s scientists established two ultra-precise fundamental constants that received worldwide recognition: the speed of light and the laser light range finder for clarifying large and extra-large lengths.
On February 24th, 2022, at 5 am, the clock of the Institute of Metrology set the launch of Russia’s full-scale invasion of Ukraine. Explosions shook Kyiv, Kharkiv, Odesa, Mariupol, and many other cities. On May 1st, the shelling of the Russian army damaged the old building of the Institute of Metrology. It was the institute’s research and education centre, founded in 1927.
The site that once held memories may now turn into a memory itself.
