摘要： The invention aims to suppress an effect of noise and heat generated from a memory on a measurement result in an ion concentration measuring device that uses an ion detection element for outputting a potential corresponding to the concentration of ions. The ion concentration measuring device according to the invention includes a cartridge having an ion detection element and a memory and supplies power to the memory in a time period excluding a time period for which the potential generated by the ion detection element is acquired.
