As part of the programme to develop low-cost instruments for use in educational institutions, we have developed a heat-flux differential scanning calorimeter (HF-DSC). We have used low cost components for building the parts of the calorimeter and they were fabricated by the local industries. The paper describes the design and construction of the calorimeter and measurement electronics in detail. The calorimeter was calibrated for temperature and enthalpy measurements using high purity metal standards. The results indicate that the on-set temperatures of thermal events can be measured with an accuracy of ± 0.7 °C and the enthalpy values within ± 3%. The sensitivity of the instrument is about 4 to 5 times lower than that obtained in a typical commercial DSC unit.

作为开发用于教育机构的低成本仪器的计划的一部分，我们开发了热通量差示扫描量热仪（HF-DSC）。我们使用了低成本的零件来制造量热仪的零件，这些零件是由当地工业制造的。本文详细介绍了量热仪和测量电子设备的设计和构造。使用高纯度金属标准品对量热仪进行了温度和焓测量校准。结果表明，可以以±0.7°C的精度测量热事件的起始温度，并且焓值在±3％以内。该仪器的灵敏度比典型的商用DSC装置低约4至5倍。
