微量水份测量仪中,电解池的性能直接影响仪器的测量准确度。所以对电解池的维护是十分重要的。在实际测量过程中,由于通过电解池的气体往往带有少量粉尘,电解池极易污染,使其性能下降。所以,在使用说明书中规定,仪器连续使用时间累计达三个月时,电解池应作再生处理。某厂生产的USI-1A型数字式微量水份仪的说明书上介绍再生处理过程是:首先用浓盐酸或王水洗涤电解池,然后用10%的磷酸涂敷,最后脱水(即干燥),即将涂敷好的电解池的一端封死,另一端与真空泵联结,抽真空两小时使其脱水干燥。该方法虽然所需时间短,但涂敷的效果不
Trace moisture meter, the electrolytic cell performance directly affects the measurement accuracy of the instrument. Therefore, the maintenance of electrolytic cells is very important. In the actual measurement process, due to the gas through the electrolytic cell often with a small amount of dust, the electrolytic cell is extremely easy to pollution, so that performance degradation. Therefore, the instructions for use, the instrument continuous use of time accumulated up to three months, the electrolytic cell should be recycled. A factory production USI-1A digital trace moisture meter manual describes the regeneration process is: first with concentrated hydrochloric acid or aqua regia electrolysis, and then coated with 10% phosphoric acid, and finally dehydrated (ie, dry), One end of the electrolytic cell to be coated is sealed and the other end is connected to a vacuum pump and evacuated for two hours to be dehydrated and dried. Although this method requires less time, the effect of coating is not
