A measuring device includes: a support which supports a measurement target object; a furnace which heats the measurement target object; an elevating mechanism which moves the furnace; and an electronic balance which measures the weight of the measurement target object, the elevating mechanism moving the furnace so that the measurement target object which is supported by the support is housed in the furnace.

Provided is a moisture meter including a mass measurement unit for measuring the mass of a specimen, a heater for heating the specimen, a control arithmetic unit configured to control the heating unit to heat the specimen until a change in the mass of the specimen becomes not more than a predetermined threshold and calculate the moisture content of the specimen, a timepiece for measuring a heating time, and a storage unit. The control arithmetic unit measures the moisture content of a standard substance for inspection and a heating time, diagnoses the presence/absence of an abnormality in the heating unit by comparing a measured heating time with a predetermined time as a set heating time stored in the storage unit in advance

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.

A method for adjusting parameters of a device with a weighing sensor collecting environmental parameter data of an environment where the device is currently located or environmental parameter data during execution of an application by the device. A zero compensation parameter is calculated and updated, based on the data collected. The method is applicable to a moisture analyzer and also to a vehicle scale. In the moisture analyzer, the method is triggered and executed in the analyzer, correcting the zero compensation data by using the environmental parameter data of an environment or environmental parameter data during execution of an application by the analyzer. Dynamic and real-time adjustment of a compensation parameter overcomes the problem that the scheme of pre-setting fixed parameters for zero compensation cannot deal with the complex zero drift encountered in actual environments.

The disclosure relates to a survey method of soil carbon stock in vegetated coastal wetlands, which excludes the influence of plant's fine roots when estimating the soil carbon stock, and effectively avoids double counting organic carbon stock of the fine roots in soil carbon stock surveys. At the same time, this method does not require bulk density calculation, which reduces the influence of sample volume compression during sample processing when calculating bulk density and provides a more accurate survey method for the study of coastal wetland carbon stock.

Methods and systems for correction of water content measurements include determining an apparent water content measurement of a sample material while the sample material is dried in ambient vapor pressure conditions, determining a correction value that represents a relationship between the apparent water content and the vapor pressure, and correcting the apparent water content measurement based on the correction value. These methods and systems can reduce cost, measurement time, and error in water content measurement for products that lose water over time, such as while being dried or cured.

Systems and methods include testing the weight and water activity of a product at different times and using those measurements to track changes in the water content/water weight and non-water content/non-water weight in the product. These can be useful to detect anomalous activities or batches of processed product, such as when portions of a product are being stolen or improperly altered or wasted. Plant operators can track properties of a product as the product undergoes processing to detect stages and areas in which problems occur and can thereby improve plant and operator efficiency.

A meat product fat testing system (MPFTS) for determining the percent fat content of a meat product. The MPFTS includes two embodiments: a fat testing/analyzing unit and a hand-held calculating unit. The fat testing/analyzing unit integrally houses a heating means, meat product weighing means, a fat/moisture analyzer, a microcontroller, and a display. A sample of a meat product is placed into the unit and the unit is activated. The percent fat content of the sample is automatically analyzed and the result shown on the unit's display. The hand-held calculating unit is used with a conventional scale and heat source, which are used to obtain wet and dry weight readings of a meat product sample. The readings are input into the calculating device, which then displays in a window the percent fat content of the sample.

A thermo-gravimetric analysis system includes a chamber having an interior; and a sample crucible connected to and inside of the chamber, the sample crucible configured to hold a sample material. The system further includes a reference crucible connected to and inside of the chamber; and a metal organic framework (MOF) crucible connected to and inside of the chamber, separate from the sample crucible, the MOF crucible including an MOF material.
