将模拟量转换为数字量的模数转换技术,在数字化测量设备以及计算机数字量采集中应用得十分广泛。在电化学分析仪器中,各种数字式仪表也日益增多。例如上海第二分析仪器厂近年研制的 PHS-3数字式酸度计、PXS-201数字式离子活度计、SJS-701携带式数字水质监测仪等,都是数字式仪表。随着我国科学技术的发展,对于电化学分析仪器提出了新的要求,不仅要求数字化,而
Analog to digital conversion digital-analog conversion technology, digital measurement equipment and computer digital acquisition is widely used. In electrochemical analysis instruments, a variety of digital instruments are also increasing. For example, Shanghai Second Analytical Instrument Factory PHS-3 digital pH meter developed in recent years, PXS-201 digital ion activity meter, SJS-701 portable digital water quality monitor, are all digital meters. With the development of science and technology in our country, new requirements are put forward for electrochemical analysis instruments, which not only require digitization, but also
