Claims (1)
- プラント配管内を流れる水中における材料の腐食電位を測定するための装置であって、
前記プラント配管に接続し、前記プラント配管内を流れる水中における材料の腐食電位を測定する腐食電位計と、
前記腐食電位計に接続し、酸素濃度の既知な校正用の純水を貯水した腐食電位校正用大気飽和水注入部とを備え、
前記腐食電位計の校正時には、
前記腐食電位校正用大気飽和水注入部は、前記校正用の純水と前記プラント配管内の水とを各々単独あるいは混合して前記腐食電位計に注入し、
前記腐食電位計は、前記プラント配管に接続したままで校正を行い、
前記腐食電位計に接続する配管の口径を、前記プラント配管に対して細めることによって前記プラント配管から分岐した水の流速を増し、前記プラント配管との分岐部から前記腐食電位計との間における配管内での水の状態の変化を低減すると共に、前記腐食電位の測定値の精度を向上させる
ことを特徴とする腐食電位測定装置。
