摘要
研制了船用pH计检定装置。以基准电压集成电路作为电压标准,以单片机为控制中心,组成船用pH计检定核心部分,控制船用pH计检定装置输出标准电位。检定装置的pH值输出范围:0～14.0000 pH;pH示值误差:0.0003 pH;电压输出范围:-1999.99～+1999.99 mV;电压分辨率:0.01 mV;温度补偿范围:0～99.9℃。
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℃.
