摘要：
PROBLEM TO BE SOLVED: To enhance the accuracy of measurement.SOLUTION: A product meter comprises a pair of sealed spaces 2R and 2C of which one is loaded with a sample 1 for generating gas a resin-made connecting block 4 having a pair of gas passages 3R and 3C to which the pair of sealed spaces 2R and 2C are detachably connected a pressure balance measuring instrument 5 whose two ends are connected to the pair of gas passages 3R and 3C, and that shifts according to the difference in pressure between the paired gas passages 3R and 3C and has a sign 5a whose position can be recognized from outside a volume varying means 7 that varies the volume of a series of gas reservoir spaces 6 formed of the sealed space 2R containing the sample 1 and a space communicating with it thereby to maintain the state thereof and a level gauge 8 that is connected to the gas reservoir spaces 6 and measures variations in gas quantity according to the up and down variations of a liquid level.COPYRIGHT: (C)2012,JPO&INPIT【課題】測定精度を向上させる。【解決手段】片方にガスを発生させる試料1が入れられる一対の密閉空間2R,2Cと、一対の密閉空間2R,2Cが着脱可能に接続される一対のガス通路3R,3Cを有する樹脂製の接続ブロック4と、両端に一対のガス通路3R,3Cが接続され、一対のガス通路3R,3Cの圧力差に応じて移動し且つ外から位置確認可能な目印5aを有する圧力バランス測定器5と、試料1を入れた密閉空間2Rとこれに通じる空間とで形成される一連のガス溜め空間6の容積を変化させてその状態を維持する容積変化手段7と、ガス溜め空間6に接続され、液面の上下変動によってガス量の変化を測定するレベルゲージ8を備えている。【選択図】図1
