FIELD: chemistry.
SUBSTANCE: invention relates to heat measurement and is meant for controlling characteristics of thermocouples. Invention is aimed at obtaining material for calibrating thermocouples, which provides for prolonged maintenance of temperature of 100±0.1°C without excessive heating. This result is achieved due to that, the material for calibrating thermocouples, containing water as standard substance, in accordance with the invention contains a hydroscopic polymer - polyacrylic acid with the following ratio of components, wt %: polyacrylic acid - 0.5-20, water - the rest.
EFFECT: no excessive heating.
