Abstract

This article shows a detailed description of the construction and calibration of a heat conduction
microcalorimeter, with thermopiles as heat flux sensors and with a metallic reaction cell. The
microcalorimeter was developed to determine small thermal effects applicable to various physical
and chemical processes. The electrical calibration results show stability between 5 to 10 µV, the
calibration constant whose value is between (13.15 ± 0.43) W V-1 and (15.24 ± 0.28) W V- 1 and the
sensitivity of about 0.066 V W-1. The chemical calibration of the equipment to establish its correct
operation was carried out with the HCI-NaOH and HCI--THAM systems, whose heats of reaction were
respectively (-56.64 ± 0.01) kJ mol-1 and (-49.56 ± 0.01) kJ mol-1.
