The Acylic Oxygen Flow Flowmeter will need to be placed vertically when working.
Please do not place the instrument in parallel when the flow meter is working, otherwise the measurement result will be inaccurate.
The gas will enter from the lower hole and exit from the upper hole to achieve the measurement effect.
Note:
If you are not familiar with the product information, you can contact seller before purchasing.
The color of the item may vary slightly due to photography and your own computer.
Warm tips:
The tubing tip is dipped in hot water where it softens that will slide on to tip easily, then you can tighten for a good grip as it cools. (be careful with hot water)
