自美国orion公司901型离子分析仪问世以来,已陆续出现了一些微机控制的离子活度计。我们在PXS-215型0.1 mV级pH计基础上,采用较强功能的Rockwell 6500微机,设计研制了PXSJ-216型离子分析仪,达到了预期目标。 PXSJ—216型离子分析仪是由双高阻放大器、A/D转换器、微机,LED、输入键盘 Since the advent of the 901 Ion Analyzer from the Orion Company in the United States, some microcomputer-controlled ion-activity meters have appeared one after another. Based on the PXS-215 0.1 mV pH meter, the PXSJ-216 ion analyzer was designed and developed with a powerful Rockwell 6500 microcomputer to achieve the expected target. PXSJ-216 ion analyzer is a dual high-impedance amplifier, A / D converter, microcomputer, LED, enter the keyboard
