摘　　要：模拟信号电极存在标定、维护等一系列问题,长时间来一直没有得到解决。自恩德斯豪斯公司生产出数字式电极以后,这一现状才得以解决。通过与传统的模拟信号电极对比,详细论述了恩德斯豪斯公司生产的数字式pH测量系统各组成的优点,从技术、维护、成本等方面阐述了它的优越性,根据现场实际应用情况论述了数字式pH测量系统的稳定性、可靠性、适应性、准确性,该系统适用于各个行业的pH值的测量。A series of problems about the maintenance and the calibration existing in analog signal electrode haven＇t been solved for a long time. Since the digital electrode produced by Endress ＋ Hauser, this situation has been changed. Compared with the traditional analog signal electrode, the advantages of digital pH measurement system produced by Endress ＋ Hauser were discussed in detail. Its superiority in the aspects of technology, maintenance and cost, etc. , was illustrated. The practical application on field proves the stability, reliability, adaptability and accuracy of digital pH measurement system. The system is suitable for various industries demanding pH measurement.
