Abstract: Provided is an electronic balance of electromagnetic force type including a weight automatic loading mechanism which can place and remove a weight by its own mechanism without use of either an external balance weight or a built-in balance weight. An electronic balance of electromagnetic force type is provided with a beam equilibrium setting unit that sets two or more equilibrium states of the beam position detecting unit. By making conversion ratios of upper and lower light receiving circuits nonequivalent, an imaginary weight is generated by utilizing the operating principle of the electromagnetic balance of electromagnetic force type.

Abstract: 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.
