ABSTRACT:
A thermogravimetric instrument for measuring variations in the weight of a sample caused by temperature variations of the sample. The instrument is equipped with a stopper mechanism for protecting the pivot to facilitate replacing a balance beam. A thermogravimetric instrument comprising: a balance beam 1 placed horizontally; a sample holder 9 located at one end of said balance beam; a torsion wire 3 mounted as a pivot and connected with the other end; a junction portion permitting a sample container side of the balance beam to be detached; and one or more stopper mechanisms using fixed stoppers 4 and metal plates 5. The stopper mechanisms limit relative movement between a supported portion of the torsion wire and the balance beam to within a prescribed amount to limit force applied to the torsion wire during detachment of the balance beam.
