Thermobalance (thermo-balance)

Japanese: 熱てんびん(熱天秤) - ねつてんびん（英語表記）thermo‐balance

A device used to measure the change in mass of an object at high temperatures as a function of temperature and time, thereby determining the thermal properties of the material. It generally consists of a balance, an electric furnace, and a temperature control and measurement section. Because the balance is affected by heat, a special balance with a quartz beam, which has a low coefficient of expansion, was used. However, advances in insulation technology have made it possible to use various general-purpose balances (manual balances, direct reading balances, electronic balances, etc.), and electronic balances, which are easy to use for automatic and remote measurement, are preferred.

高温下における物体の質量変化を温度と時間の関数として測定し，物質の熱的性質を知るのに用いる装置。一般に，てんびん，電気炉および温度の制御･測定の各部で構成される。てんびんは熱的影響を受けるので膨張係数の小さい石英製のさおを用いた特殊なてんびんを用いたが，断熱技術の進歩により各種の汎用（はんよう）てんびん(手動てんびん，直示てんびん，電子てんびんなど)が使用できるようになり，自動測定，遠隔測定の容易な電子てんびんが賞用されている。
