Актуальность работы обусловлена широтой применения изотермических калориметров титрования, реализующих данный метод, и отсутствием стандартизованных метрологических процедур и инструментов метрологического обеспечения. Для решения проблемы обеспечения единства и прослеживаемости измерений в указанной области лабораторией калориметрии ВНИИМ проведены исследования с целью расширения функциональных и измерительных возможностей Государственного первичного специального эталона единицы количества теплоты в области калориметрии растворения и реакций ГЭТ 133-2012. В ходе работ разработан, исследован и включён в состав усовершенствованного ГЭТ 133-2012 эталонный микрокалориметр титрования МКТ, предназначенный для воспроизведения, хранения и передачи единицы количества теплоты в области измерений малых тепловых эффектов в жидких средах. В результате исследований микрокалориметра МКТ подтверждена возможность воспроизведения и передачи единицы количества теплоты в диапазоне 100–5000 мкДж с расширенной неопределённостью 1,2–8,6 %. Усовершенствованный ГЭТ 133-2012 с обновленным составом и новыми метрологическими характеристиками утверждён как Государственный первичный специальный эталон единицы количества теплоты в области калориметрии растворения и реакций ГЭТ 133-2023. Расширение эталонной базы в области изотермической калориметрии титрования позволило заложить основы для создания новых метрологических средств передачи единицы количества теплоты в области калориметрии растворения и реакций.</p></abstract><trans-abstract xml:lang="en"><p>The article shows the need to develop methods and tools for realization and transferring a unit of heat quantity in the fi eld of measuring small thermal effects of physical and chemical interactions  by the method of isothermal titration calorimetry. The relevance of the work is due to the wide application of measuring instruments implementing this method and the lack of standardized metrological procedures and tools. To solve the problem of ensuring unity and traceability of measurements in this fi eld, VNIIM calorimetry laboratory conducted research to expand the functional and measuring capabilities of the State primary special standard of the unit of heat quantity in the fi eld of solution and reaction calorimetry GET 133-2012. In the course of work a reference titration microcalorimeter MKT was developed, investigated, and included in the GET 133-2012. Microcalorimeter MKT was designed to realize, store, and transfer a unit of heat quantity in the fi eld of measuring small thermal effects in liquid media. As a result of microcalorimeter studies, the capability of realizing and transferring a unit of heat quantity in a new range was confi rmed: from 100 to 5000 μJ with an expanded uncertainty from 1.2 to 8.6 %. The improved GET 133-2012 with an updated composition and new metrological characteristics was approved as the State primary special standard of the unit of heat quantity in the fi eld of solution and reaction calorimetry GET 133-2023. This lays the foundations for the creation of new metrological tools and procedures for transferring the unit of heat quantity in the fi eld of solution and reaction calorimetry.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>изотермическая калориметрия титрования</kwd><kwd>неопределённость измерений</kwd><kwd>химическая калибровка калориметров</kwd><kwd>государственный первичный специальный эталон</kwd><kwd>количество теплоты</kwd><kwd>прослеживаемость измерений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>isothermal titration calorimetry</kwd><kwd>measurement uncertainty</kwd><kwd>calorimeter chemical calibration</kwd><kwd>state primary special standard</kwd><kwd>heat quantity</kwd><kwd>metrological traceability</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kabiri M., Unsworth L.
