| Abstract: | The verification device of shipboard pH meter was developed. The verification device of ahipboard pH meters was controlled to generate standard voltage by SCM controller center with benchmark voltage IC. The verification device of pH output ranged from 0 to 14.0000 pH. pH indication error was 0. 0003 pH. Potential output ranged from -1 999.99 to ＋ 1 999.99 mV. Potential resolution was 0.01 mV and temperature compensation range was 0 -99.9℃. |
