Abstract

A conduction calorimeter with a thermally stable heat sink and six measurement cells have been designed and constructed. In order to make a compact calorimeter which is easy to operate in application to quality control of industrial materials such as cement, temperature of the aluminum heat sink was controlled directly using Peltier effect of Thermomodule. Temperature fluctuation of the heat sink was within ±0.1 ℃ during 8 days of continuous measurement accompanying large exothermic heat of reaction. Les than 40 μV/24h（1.38×10 ^－3℃）and 20 μVp-p（±0.69×10 ^－3℃）were achieved for base line drift and thermal noise, respectively. Both accuracy and reproducibility were estimated to be better than 0.5 %. Interference between the neighboring cells was negligible in simultaneous measurement of six samples. It was confirmed that the developed calorimeter was successfully applicable to measurement of industrial materials with extremely low reaction rate.
