Abstract
Description
特定の気体を透過する配管でありかつ該特定の気体の水溶液が流通する配管に固定されて該配管中を流通する該水溶液に溶存する該特定の気体の濃度を測定する溶存気体測定装置であって、
前記配管に前記溶存気体測定装置を固定する配管押さえ部と、
前記配管を透過した気体を貯留する空間であるガス貯留部と、
前記ガス貯留部に貯留された気体を換気する換気筒とを備え、
前記換気筒は、前記ガス貯留部から該換気筒に流入した前記特定の気体の濃度を測定する気体センサーと、該気体を該換気筒外に排出する換気口とを有しており、
前記ガス貯留部と前記換気口との間をつなぎ該ガス貯留部から該換気筒に流入した前記特定の気体が流通可能な流路であって、該ガス貯留部から該換気口に向かって絞られている流路を備え、
前記気体センサーは、前記ガス貯留部と前記換気口との間に位置するように、前記流路内に配置されていることを特徴とする。
これにより、配管を透過してガス貯留部から換気筒に流入した特定の気体は、換気筒外に自然換気されるときに、必ず当該特定の気体の濃度を測定する気体センサーにより測定されるので、配管中を流通する気体の水溶液中に溶存する気体の濃度を効果的に測定することができる。
前記換気筒は、前記配管押さえ部の前記配管方向における一方の端部側に配置されていることが好ましい。
