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.

Provided is a protective cover for a weighing instrument in which movement of a sliding door does not degrade over time. A protective cover () for a weighing instrument includes sliding doors (L,R) defining a weighing chamber (), an upper frame () formed at an upper edge of the sliding door, a lower frame () formed at a lower edge of the sliding door, an upper guide rail () disposed on the upper frame, and a lower guide rail () disposed under the lower frame, where the upper guide rail suspends the upper frame, and between the upper guide rail and the upper frame, balls () are disposed at a plurality of positions in a moving direction of the sliding door.

Provided are a method and device for improving a response speed in a measurement of viscosity of a fluid and obtaining a continuous smooth measurement graph. A viscometer includes a machine part that generates a shear rate in a sample, a machine drive, a shear rate changing means that outputs a target shear rate of the machine part, and a displacement detection sensor that measures displacement of the machine part, and performs feedback control to control a driving force of the machine drive so that an output value of the displacement detection sensor corresponds to the target shear rate and measures a viscosity of a sample, wherein a feedback gain is simply set for each measurement according to an optimum design or target shear rate.
