Infi Imported,Accurate And Durable Oxygen Regulator With Humidifier Bottle And Spanner Suitable For B Type And D Type Cylinders

Works as expected. Earlier Spanner was missing and later seller shipped in different courier. Thanks.

Ease of use and calibration makes it a great purchase. Worth the money.

Initially they had not given the humidifer bottle and key as mentioned in product description! But later the missing items were sent through a seperate courier.

These flow meters are good to use but they have few weak spare components and once they break, you cannot even find replacement and whole product become useless.

Very good product good quality.very good during emergency

Very good quality prompt delivery
