摘要： A measuring method of determining component concentration in a solution by calculating component concentrations in the solution at various temperatures in a small number of steps. The component concentration is measured at an arbitrary temperature T by using a solution absorbance spectrum and solvent absorbance spectrum at a plurality of wavelength(s)r, and preliminarily determining a calibration coefficient Mij (TO). Concentration of Ci of component i in solution at reference temperature TO, is obtained at differential spectrum of solution spectrum S (λj, T) at temperature T in j-th wavelength λj and solvent spectrum B (λj, T) at temperature T in j-th wavelength λj, calculating calibration coefficient Mij (TO) the specific component concentrations.

摘要： A flat shaped composite electrode includes a flat substrate having a high electrical insulating property. A flat inside pair of electrodes and a flat outside pair of electrodes are fixed on the substrate. A flat support layer having a high electrical insulating property overlays the electrodes and substrate. The support layer describes two holes into which a gelatinized internal solution is placed. An ion response glass membrane is mounted on the support layer and over one hole, while a liquid junction membrane is similarly mounted over the other hole.

摘要： The direction of change of an analog signal which is digitally displayed on a digital display can be immediately determined at a glance by providing a change-display in the vicinity of the digital display, which digitally displays the analog signal value. The change-display displays whether the analog input signal is increasing or decreasing by comparing the present value of the input signal with a previous value thereof. This comparison may be effected by integrating the input signal and comparing the integrated input signal with the input signal or by differentiating the input signal or by using a sample and hold circuit to hold a previous input signal value which is then compared with the present input signal value.

摘要： A device for measuring ionic concentration in a sample liquid, having a detachable waterproof electrode housing. A body member has a computing device disposed therein and a display panel on an exterior surface. The waterproof electrode housing is demountably coupled to the body member. The electrode housing includes a flat surface sensor capable of measuring ionic concentration of the sample liquid when the device is placed on a flat surface, and is waterproof for measuring ionic concentration by immersion. A gap is formed between the body and the flat surface for preventing water from entering the body when the flat surface ionic concentration measurement procedure is being conducted.
