<P>PROBLEM TO BE SOLVED: To provide an inexpensive measuring system calibrating a sensor easily. <P>SOLUTION: This PH measuring system includes a measuring device body 1, a sensor module 2A mountable on/dismountable from the measuring device body 1, and a PH sensor 3A connected to the sensor module 2A. The sensor module 2A includes an amplifier 21 for amplifying an analog signal from the PH sensor 3A, an AD converter 22 for converting an analog signal amplified by the amplifier 21 into a digital signal, a control part 23 for executing control necessary for measurement operation in the sensor module 2A, and a nonvolatile memory 24 for storing calibration information of the PH sensor 3A. <P>COPYRIGHT: (C)2010,JPO&INPIT |
