High-accuracy type purgemeter for measuring liquids
and gases

P-200Purgemeter■ OUTLINEThe P-200 is a standard type purgemeter with a face-to-face dimension of 200mm, which is the same as the P-510 for large ﬂ ow rates. The P-200 features highaccuracy with an easy-to-see large scale and thus is widely used for experiments
and in other ﬁelds.
