A measuring instrument for thermogravimetrically determining the moisture content of a material, which includes a base (12), configured as a balance, with a base surface (22), and a hood (14) pivotably connected to the base. The hood has a weighing chamber lid (50), weighing chamber walls (52-56) and a heating element (44). The hood consists of an electronics module (36) that includes the heating element and an electronic power unit, and of a mechanical module (48) that includes the weighing chamber lid and all of the weighing chamber walls. The mechanical module (48) is rigidly and reversibly coupled to the electronics module so that the heating element, protrudes from a main body (42) of the electronics module and rises through a corresponding opening (58) in the rearward weighing chamber wall (56), with the main body being pivotably connected to the base and surrounding the electronic power unit.

The analyzer mixes the material to be analyzed and the flux in sample holders supported by a moveable platform within the furnace. A tilt member is provided having multiple stations. Each station has an upstanding pin offset from the center point of the station in a different direction. The platform is indexed relative to the tilt member such that the sample holder aligns with each station, in sequence. As the sample holder aligns with each station, the platform is moved toward the tilt member such that the pin of the aligned station abuts and tilts the sample holder in a different direction. The repeated tilting of the sample holder in different directions mixes the material and flux. The contents of the sample holder may also be agitated by rapidly moving the platform back and forth with sudden stops. The analyzer can be used with a special sample holder.

Provided is a moisture meter includes a mass scale for measuring a mass of a specimen, a heater for heat the specimen, a processor causes the moisture meter to control the heater to heat the specimen until a change in mass of the specimen becomes not more than a predetermined threshold and calculate a moisture content of the specimen, and a storage unit. The processor causes the moisture meter to execute a measurement of a moisture content a plurality of times by using, as the specimen, a standard substance for inspection having a predetermined theoretical moisture content with an arbitrary mass when being heated at a predetermined temperature, to calculate a standard deviation of a measured moisture content in the measurement executed the plurality of times, and a to evaluate an influence of an installation environment by determining whether the standard deviation is not more than a predetermined value.
